An explicit cast is still needed in tbmintrin.h to convert any big integer down to i32imm.

This is useful for some ARM intrinsics such as VCVTN which does a <4 x float> <-> <4 x half> conversion.

Found this with asan. Code assumes that find doesn't return end, thus if
both atoms didn't have followon roots it would still compare their positions.

Don't vectorize with a runtime check if it requires a
comparison between pointers with different address spaces.
The values can't be assumed to be directly comparable.
Previously it would create an illegal bitcast.

disassembled output alongside the instructions.
E.g., on a vector shuffle operation with a memory operand, disassembled
outputs are:
* Without the option:
    vpshufd $-0x79, (%rsp), %xmm0
    
* With the option:
    vpshufd $-0x79, (%rsp), %xmm0   ## Latency: 5

The printed latency is extracted from the schedule model available in the
disassembler context. Thus, this option has no effect if there is not a
scheduling model for the target.
This boils down to one may need to specify the CPU string, so that this
option could have an effect.

Note: Latency < 2 are not printed.

CodeGenTypes already has a reference to a CGCXXABI. Use this directly
rather than going through CodeGenModule to get to the same information.

This is consistent with other references to CGCXXABI in CodeGenTypes
functions defined in CGCall.cpp.

This recursively strips all GEPs like the existing code. It also handles bitcasts and

Switch instructions were crashing the StructurizeCFG pass, and it's
probably easier anyway if we don't need to handle them in this pass.

infrastructure.

This was essentially work toward PGO based on a design that had several
flaws, partially dating from a time when LLVM had a different
architecture, and with an effort to modernize it abandoned without being
completed. Since then, it has bitrotted for several years further. The
result is nearly unusable, and isn't helping any of the modern PGO
efforts. Instead, it is getting in the way, adding confusion about PGO
in LLVM and distracting everyone with maintenance on essentially dead
code. Removing it paves the way for modern efforts around PGO.

Among other effects, this removes the last of the runtime libraries from
LLVM. Those are being developed in the separate 'compiler-rt' project
now, with somewhat different licensing specifically more approriate for
runtimes.

Summary:
As discussed in http://llvm-reviews.chandlerc.com/D1754,
this optimization isn't really valid for C, and fires too rarely anyway.
