Jim Grosbach 1152cc0cad ARM asm parser should be more lenient w/ .thumb_func directive.
Rather than require the symbol to be explicitly an argument of the directive,
allow it to look ahead and grab the symbol from the next non-whitespace
line.

Jakob Stoklund Olesen b95c102c2f Heed spill slot alignment on ARM.
Use the spill slot alignment as well as the local variable alignment to
determine when the stack needs to be realigned. This works now that the
ARM target can always realign the stack by using a base pointer.

Still respect the ARMBaseRegisterInfo::canRealignStack() function
vetoing a realigned stack.  Don't use aligned spill code in that case.

Chandler Carruth 24680c24d8 Begin teaching the X86 target how to efficiently codegen patterns that
use the zero-undefined variants of CTTZ and CTLZ. These are just simple
patterns for now, there is more to be done to make real world code using
these constructs be optimized and codegen'ed properly on X86.

The existing tests are spiffed up to check that we no longer generate
unnecessary cmov instructions, and that we generate the very important
'xor' to transform bsr which counts the index of the most significant
one bit to the number of leading (most significant) zero bits. Also they
now check that when the variant with defined zero result is used, the
cmov is still produced.

Bob Wilson 75f12cc3fe Mark ARM eh_sjlj_dispatchsetup as clobbering all registers. Radar 10567930.
We used to rely on the *eh_sjlj_setjmp instructions to mark that a function
with setjmp/longjmp exception handling clobbers all the registers.  But with
the recent reorganization of ARM EH, those eh_sjlj_setjmp instructions are
expanded away earlier, before PEI can see them to determine what registers to
save and restore.  Mark the dispatchsetup instruction in the same way, since
that instruction cannot be expanded early.  This also more accurately reflects
when the registers are clobbered.

Jim Grosbach e2ca9e5b5f ARM assembly shifts by zero should be plain 'mov' instructions.

Jakob Stoklund Olesen 5af144809e Don't adjust for alignment padding in OffsetIsInRange.
This adjustment is already included in the block offsets computed by
BasicBlockInfo, and adjusting again here can cause the pass to loop.

the new CPE on the next pass because of the too conservative alignment
adjustment. This caused the block to be split again, and so on.

Chandler Carruth 637cc6a8aa Initial CodeGen support for CTTZ/CTLZ where a zero input produces an
undefined result. This adds new ISD nodes for the new semantics,
selecting them when the LLVM intrinsic indicates that the undef behavior
is desired. The new nodes expand trivially to the old nodes, so targets
don't actually need to do anything to support these new nodes besides
indicating that they should be expanded. I've done this for all the
operand types that I could figure out for all the targets. Owners of
various targets, please review and let me know if any of these are
incorrect.

Note that the expand behavior is *conservatively correct*, and exactly
matches LLVM's current behavior with these operations. Ideally this
patch will not change behavior in any way. For example the regtest suite
finds the exact same instruction sequences coming out of the code
generator. That's why there are no new tests here -- all of this is
being exercised by the existing test suite.

Thanks to Duncan Sands for reviewing the various bits of this patch and
helping me get the wrinkles ironed out with expanding for each target.
Also thanks to Chris for clarifying through all the discussions that
this is indeed the approach he was looking for. That said, there are
likely still rough spots. Further review much appreciated.

Evan Cheng 4d1a2d449f 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

Jakob Stoklund Olesen 2a82333f54 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.

For properties like isPredicable, only return true if *all* of the bundled

For properties like canFoldAsLoad, isCompare, conservatively return false for
