94c2e85bea The second part of support for generating dwarf for assembly source files. This 
generates the dwarf Compile Unit DIE and a dwarf subprogram DIE for each
non-temporary label.

The next part will be to get the clang driver to enable this when assembling
a .s file.  rdar://9275556

5d73448bb7 Add -unroll-runtime for unrolling loops with run-time trip counts. 
Patch by Brendon Cahoon!

This extends the existing LoopUnroll and LoopUnrollPass. Brendon
measured no regressions in the llvm test suite with -unroll-runtime
enabled. This implementation works by using the existing loop
unrolling code to unroll the loop by a power-of-two (default 8). It
generates an if-then-else sequence of code prior to the loop to
execute the extra iterations before entering the unrolled loop.

2f435511e9 Many of the SSE patterns should not be selected when AVX is available. This led to the following code in X86Subtarget.cpp 
if (HasAVX)
    X86SSELevel = NoMMXSSE;

This is so patterns that are predicated on hasSSE3, etc. would not be selected when avx is available. Instead, the AVX variant is selected.
However, this breaks instructions which do not have AVX variants.

The right way to fix this is for the SSE but not-AVX patterns to predicate on something like hasSSE3() && !hasAVX().
Then we can take out the hack in X86Subtarget.cpp. Patterns which do not have AVX variants do not need to change.

However, we need to audit all the patterns before we make the change. This patch is workaround that fixes one specific case,
the prefetch instructions. rdar://10538297

540c6d9d26 Don't include alignment padding in BBInfo.Size. 
Compute alignment padding before and after basic blocks dynamically.

Heed basic block alignment.

This simplifies bookkeeping because we don't have to constantly add and
remove padding from BBInfo.Size.  It also makes it possible to track the
extra known alignment bits we get after a tBR_JTr terminator and when
entering an aligned basic block.

This makes the ARMConstantIslandPass aware of aligned basic blocks.

It is tricky to model block alignment correctly when dealing with inline
assembly and tBR_JTr instructions that have variable size.  If inline
assembly turns out to be smaller than expected, that may cause following
alignment padding to be larger than expected.  This could cause constant
pool entries to move out of range.

To avoid that problem, we use the worst case alignment padding following
inline assembly. This may cause slightly suboptimal constant island
placement in aligned basic blocks following inline assembly.  Normal
functions should be unaffected.

as the MC layer API.

For properties like mayLoad / mayStore, look into the bundle and if any of the

For properties like isPredicable, only return true if *all* of the bundled
instructions have the property.
For properties like canFoldAsLoad, isCompare, conservatively return false for
bundles.

d25c27807e Use conservative size estimate for tBR_JTr. 
This pseudo-instruction contains a .align directive in its expansion, so
the total size may vary by 2 bytes.

It is too difficult to accurately keep track of this alignment
directive, just use the worst-case size instead.

305e5fe797 Remove alignment from deserted constant islands. 
ARMConstantIslandPass may sometimes leave empty constant islands behind
(it really shouldn't). Remove the alignment from the empty islands so
the size calculations are still correct.

This should fix the many Thumb1 assembler errors in the nightly test
suite.

The reduced test case for this problem is way too big. That is to be
expected for ARMConstantIslandPass bugs.

It's always good to prune early, but formulae that are unsatisfactory
in their own right need to be removed before running any other pruning
heuristics. We easily avoid generating such formulae, but we need them
as an intermediate basis for forming other good formulae.

3e572ac2fb Align ARM constant pool islands via their basic block. 
Previously, all ARM::CONSTPOOL_ENTRY instructions had a hardwired
alignment of 4 bytes emitted by ARMAsmPrinter.  Now the same alignment
is set on the basic block.

This is in preparation of supporting ARM constant pool islands with
different alignments.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145890 91177308-0d34-0410-b5e6-96231b3b80d8

8c741b8064 Use logarithmic units for basic block alignment. 
This was actually a bit of a mess. TLI.setPrefLoopAlignment was clearly
documented as taking log2(bytes) units, but the x86 target would still
set a preferred loop alignment of '16'.

CodePlacementOpt passed this number on to the basic block, and
AsmPrinter interpreted it as bytes.

Now both MachineFunction and MachineBasicBlock use logarithmic
alignments.

Obviously, MachineConstantPool still measures alignments in bytes, so we
can emulate the thrill of using as.

4da7f90b17 Add a little heuristic to Value::isUsedInBasicBlock to speed it up for small basic blocks. 
- Calling getUser in a loop is much more expensive than iterating over a few instructions.
- Use it instead of the open-coded loop in AddrModeMatcher.
- 5% speedup on ARMDisassembler.cpp Release builds.

layer of caching to the caching-heavy LVI but I don't see a better way.

199ce33b3b Check for stack space more intelligently. 
libgcc sets the stack limit field in TCB to 256 bytes above the actual
allocated stack limit.  This means if the function's stack frame needs
less than 256 bytes, we can just compare the stack pointer with the
stack limit.  This should result in lesser calls to __morestack.

40f8222e1e Fix a bug in the x86-32 code generated for segmented stacks. 
Currently LLVM pads the call to __morestack with a add and sub of 8
bytes to esp.  This isn't correct since __morestack expects the call
to be followed directly by a ret.

This commit also adjusts the relevant test-case.
