0826e1c519 Remove another memory leak from ABCD by using Edges by value instead of
pointer.  There was also a SmallPtrSet whose settiness wasn't being used, so I
changed it to a SmallVector.

6fde0bd39b When we promote a load of an argument make sure to take the alignment
of the previous load - it's usually important.  For example, we don't want
to blindly turn an unaligned load into an aligned one.

897dd0c588 Add NVMulSLFrm to represent "3-register multiply with scalar" operations and set
it as the format for the appropriate N3V*SL*<> classes.  These instructions
require special handling of the M:Vm field which encodes the restricted Dm and
the lane index within Dm.

Examples are A8.6.325 VMLA, VMLAL, VMLS, VMLSL (by scalar):

	vmlal.s32	q3, d2, d10[0]

2ad4aca8b2 If we mark clean-ups as clean-ups, then it could break when inlining through an
'invoke' instruction. You will get a situation like this:

bb:
  %ehptr = eh.exception()
  %sel = eh.selector(%ehptr, @per, 0);

...

bb2:
  invoke _Unwind_Resume_or_Rethrow(%ehptr) %normal unwind to %lpad

lpad:
  ...

The unwinder will see the %sel call as a clean-up and, if it doesn't have a
catch further up the call stack, it will skip running it. But there *is* another
catch up the stack -- the catch for the %lpad. However, we can't see that. This
is fixed in code-gen, where we detect this situation, and convert the "clean-up"
selector call into a "catch-all" selector call. This gives us the correct
semantics.

c6e704df8d Add N3RegVShFrm to represent 3-Register Vector Shift Instructions, which do not
follow the N3RegFrm's operand order of D:Vd N:Vn M:Vm.  The operand order of
N3RegVShFrm is D:Vd M:Vm N:Vn (notice that M:Vm is the first src operand).

Add a parent class N3Vf which requires passing a Format argument and which the
N3V class is modified to inherit from.  N3V class represents the "normal"
3-Register NEON Instructions with N3RegFrm.

Also add a multiclass N3VSh_QHSD to represent clusters of NEON 3-Register Shift
Instructions and replace 8 invocations with it.

0a3dc10eba Add N2RegVShLFrm and N2RegVShRFrm formats so that the disassembler can easily
dispatch to the appropriate routines to handle the different interpretations of
the shift amount encoded in the imm6 field.  The Vd, Vm fields are interpreted
the same between the two, though.

See, for example, A8.6.367 VQSHL, VQSHLU (immediate) for N2RegVShLFrm format and
A8.6.368 VQSHRN, VQSHRUN for N2RegVShRFrm format.

Feel free to LOL at the -before numbers, if you like.

I am a little surprised we make more than 2 relaxation passes. It's pretty
trivial for us to do relaxation out-of-order if that would give a speedup.

352aa503fa Add a late SSEDomainFix pass that twiddles SSE instructions to avoid domain crossings.
On Nehalem and newer CPUs there is a 2 cycle latency penalty on using a register
in a different domain than where it was defined. Some instructions have
equvivalents for different domains, like por/orps/orpd.

The SSEDomainFix pass tries to minimize the number of domain crossings by
changing between equvivalent opcodes where possible.

This is a work in progress, in particular the pass doesn't do anything yet. SSE
instructions are tagged with their execution domain in TableGen using the last
two bits of TSFlags. Note that not all instructions are tagged correctly. Life
just isn't that simple.

The SSE execution domain issue is very similar to the ARM NEON/VFP pipeline
issue handled by NEONMoveFixPass. This pass may become target independent to
handle both.

d5d5a3dcba Change tblgen to emit FOOISD opcode names as two
bytes instead of one byte.  This is important because
we're running up to too many opcodes to fit in a byte
and it is aggrevated by FIRST_TARGET_MEMORY_OPCODE
making the numbering sparse.  This just bites the
bullet and bloats out the table.  In practice, this
increases the size of the x86 isel table from 74.5K
to 76K.  I think we'll cope :)

47cdf4abff Make the NDEBUG assertion stronger and more clear what is
happening.

Enhance scheduling to set the DEAD flag on implicit defs
more aggressively.  Before, we'd set an implicit def operand
to dead if it were present in the SDNode corresponding to
the machineinstr but had no use.  Now we do it in this case
AND if the implicit def does not exist in the SDNode at all.

This exposes a couple of problems: one is the FIXME, which
causes a live intervals crash on CodeGen/X86/sibcall.ll.
The second is that it makes machinecse and licm more 
aggressive (which is a good thing) but also exposes a case
where licm hoists a set0 and then it doesn't get resunk.

Talking to codegen folks about both these issues, but I need
this patch in in the meantime.

bfcb305189 Change how dbg_value sdnodes are converted into machine instructions. Their placement should be determined by the relative order of incoming llvm instructions. The scheduler will now use the SDNode ordering information to determine where to insert them. A dbg_value instruction is inserted after the instruction with the last highest source order and before the instruction with the next highest source order. It will optimize the placement by inserting right after the instruction that produces the value if they have consecutive order numbers.
Here is a theoretical example that illustrates why the placement is important.

tmp1 = 
store tmp1 -> x
...
tmp2 = add ...
...
call
...
store tmp2 -> x

Now mem2reg comes along:

tmp1 = 
dbg_value (tmp1 -> x)
...
tmp2 = add ...
...
call
...
dbg_value (tmp2 -> x)

When the debugger examine the value of x after the add instruction but before the call, it should have the value of tmp1.

Furthermore, for dbg_value's that reference constants, they should not be emitted at the beginning of the block (since they do not have "producers").

This patch also cleans up how SDISel manages DbgValue nodes. It allow a SDNode to be referenced by multiple SDDbgValue nodes. When a SDNode is deleted, it uses the information to find the SDDbgValues and invalidate them. They are not deleted until the corresponding SelectionDAG is destroyed.

cb0f06e05c Disable folding loads into tail call in 32-bit PIC mode. It can introduce illegal code like this:
addl    $12, %esp
        popl    %esi
        popl    %edi
        popl    %ebx
        popl    %ebp
        jmpl    *__Block_deallocator-L1$pb(%esi)  # TAILCALL

The problem is the global base register is assigned GR32 register class. TCRETURNmi needs the registers making up the address mode to have the GR32_TC register class.

The *proper* fix is for X86DAGToDAGISel::getGlobalBaseReg() to return a copy from the global base register of the machine function rather than returning the register itself. But that has the potential of causing it to be coalesced to a more restrictive register class: GR32_TC. It can introduce additional copies and spills. For something as important the PIC base, it's not worth it especially since this is not an issue on 64-bit.

15417383b9 Fix memory leak in liveintervals: the destructor for VNInfos must be called,
otherwise the SmallVector it contains doesn't free its memory.
In most cases LiveIntervalAnalysis could get away by not calling the destructor,
because VNInfos are bumpptr-allocated, and smallvectors usually don't grow.
However when the SmallVector does grow it always leaks.

This is the valgrind shown leak from the original testcase:

---
>                 // Src: (X86dec_flag:i16:i32 GR16:i16:$src)

because now it knows that X86dec_flag returns both an i16 (for the result)
and an i32 (for EFLAGS) in this case.  Wewt.

df9a4f0591 Fix VLDMQ and VSTMQ instructions to use the correct encoding and address modes.
These instructions are only needed for codegen, so I've removed all the
explicit encoding bits for now; they should be set in the same way as the for
VLDMD and VSTMD whenever we add encodings for VFP.  The use of addrmode5
requires that the instructions be custom-selected so that the number of
registers can be set in the AM5Opc value.

98330ff8e3 Fix a very bad typo. Since the register number was off by one, the ARM
load/store optimizer would incorrectly think that registers D26 and D28

472fdf7090 Clear the SCEVExpander's insertion point after making deletions,
so that the SCEVExpander doesn't retain a dangling pointer as its
insert position. The dangling pointer in this case wasn't ever used
to insert new instructions, but it was causing trouble with
SCEVExpander's code for automatically advancing its insert position
past debug intrinsics.

This fixes use-after-free errors that valgrind noticed in
test/Transforms/IndVarSimplify/2007-06-06-DeleteDanglesPtr.ll and
test/Transforms/IndVarSimplify/exit_value_tests.ll.
