94ac0343cc Add extra sign extension to the same bit width before int sign
extension to another bit width. This is needed to get correct singed value.

03e9dd9ffa Change the X86 asmprinter to use the mangler to apply suffixes like "$non_lazy_ptr"
to symbols instead of doing it with "printSuffixedName".  This gets us to the point
where there is a real separation between computing a symbol name and printing it,
something I need for MC printer stuff.

This patch also fixes a corner case bug where unnamed private globals wouldn't get
the private label prefix.

Next up, rename all uses of getValueName -> getMangledName for better greppability,
and then tackle the ppc/arm backends to eliminate "printSuffixedName".

014700c1a8 Add infrastructure to allow post instruction printing action triggers.
We'll eventually use this to print comments in asm files and do other
fun things.

This adds interfaces to the AsmPrinter and changes TableGen to invoke
the postInstructionAction when appropriate.  It also add parameters to
TargetAsmInfo to control comment layout.

65a7a6f7a3 fix x86-64 static codegen to materialize the address of a global with movl instead
of lea.  It is better for code size (and presumably efficiency) to use:

  movl $foo, %eax

rather than:

  leal foo, eax

Both give a nice zero extending "move immediate" instruction, the former is just
smaller.  Note that global addresses should be handled different by the x86
backend, but I chose to follow the style already in place and add more fixme's.

4f06649497 Fix PR4533, which is about buggy codegen in x86-64 -static mode.
Basically, using:
  lea symbol(%rip), %rax

is not valid in -static mode, because the current RIP may not be
within 32-bits of "symbol" when an app is built partially pic and
partially static.  The fix for this is to compile it to:

  lea symbol, %rax

It would be better to codegen this as:

  movq $symbol, %rax

but that will come next.


The hard part of fixing this bug was fixing abi-isel, which was actively
testing for the wrong behavior.  Also, the RUN lines are completely impossible
to understand what they are testing.  To help with this, convert the -static 
x86-64 codegen tests to use filecheck.  This is much more stable and makes it
more clear what the codegen is expected to be.

446c428bf3 Major changes to Thumb (not Thumb2). Many 16-bit instructions either modifies CPSR when they are outside the IT blocks, or they can predicated when in Thumb2. Move the implicit def of CPSR to an optional def which defaults CPSR. This allows the 's' bit to be toggled dynamically.
A side-effect of this change is asm printer is now using unified assembly. There are some minor clean ups and fixes as well.

d15f45f53e If -fomit-frame-pointer is used, we still need to record when the %esp register
is modified. Otherwise, the unwinder will get confused. The old code (before I
started my hacking) did this. It dropped on the floor, because I wasn't aware of
this requirement.

On the plus side, if we use "alloca" in a function, we create frame pointers
even with -fomit-frame-pointer is enabled!

This is a Good Thing(tm)!!!

910139f9ca Targets sometimes assign fixed stack object to spill certain callee-saved
registers based on dynamic conditions. For example, X86 EBP/RBP, when used as
frame register has to be spilled in the first fixed object. It should inform
PEI this so it doesn't get allocated another stack object. Also, it should not
be spilled as other callee-saved registers but rather its spilling and restoring
are being handled by emitPrologue and emitEpilogue. Avoid spilling it twice.

dda0f4cb79 - Add some NEON ld / st instruction static encoding.
- Make bits 25-27 for ldrh, etc. explicitly zero. Previously only the JIT uses the encoding information and it's assuming anything not specified to be zero. Making them explicit so the disassembler is happy.

c3d505c3c2 Recommit r74952 with a bug fix:
DWARF requires frame moves be specified at specific times. If you have a
prologue like this:

__Z3fooi:
Leh_func_begin1:
LBB1_0: ## entry
       pushl   %ebp
Llabel1:
       movl    %esp, %ebp
Llabel2:
       pushl   %esi
Llabel3:
       subl    $20, %esp
       call    "L1$pb"
"L1$pb":
       popl    %esi

The "pushl %ebp" needs a table entry specifying the offset. The "movl %esp,
%ebp" makes %ebp the new stack frame register, so that needs to be specified in
DWARF. And "pushl %esi" saves the callee-saved %esi register, which also needs
to be specified in DWARF.

Before, all of this logic was in one method. This didn't work too well, because
as you can see there are multiple FDE line entries that need to be created.

This fix creates the "MachineMove" objects directly when they're needed; instead
of waiting until the end, and losing information.

There is some ugliness where we generate code like this:


LBB22_0:	## entry
	pushl	%ebp
Llabel280:
	movl	%esp, %ebp
Llabel281:
Llabel284:
	pushl	%ebp  <----------
	pushl	%ebx
	pushl	%edi
	pushl	%esi
Llabel282:
	subl	$328, %esp

Notice the extra "pushl %ebp". If we generate a "machine move" instruction in
the FDE for that pushl, the linker may get very confused about what value %ebp
should have when exitting the function. I.e., it'll give it the value %esp
instead of the %ebp value from the first "pushl". Not to mention that, in this
case, %ebp isn't modified in the function (that's a separate bug). I put a small
hack in to get it to work. It might be the only solution, but should be
revisited once the above case is fixed.
