Tim Northover 58672974a9 ARM & AArch64: convert asm tests to LLVM IR and restrict optimizations. 
This is mostly a one-time autoconversion of tests that checked assembly after
"-Owhatever" compiles to only run "opt -mem2reg" and check the assembly. This
should make them much more stable to changes in LLVM so they won't break on
unrelated changes.

"opt -mem2reg" is a compromise designed to increase the readability of tests
that check dataflow, while minimizing dependency on LLVM. Hopefully mem2reg is
stable enough that no surpises will come along.

Should address http://llvm.org/PR26815.

Amaury de la Vieuville 21bf6ed730 Do not emit undefined lsrh/ashr for NEON shifts 
These IR instructions are undefined when the amount is equal to operand
size, but NEON right shifts support such shifts. Work around that by
emitting a different IR in these cases.
