Jim Grosbach a50e24fcb3 ARM NEON mnemonic aliases for vzipq and vswpq.

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. 
"mov r1, r2, lsl #0" should assemble as "mov r1, r2" even though it's
not strictly legal UAL syntax. It's a common extension and the friendly
thing to do.
