Don't use runtime bounds check between address spaces.

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.

[llvm-c][Disassembler] When printing latency information, skip scheduling
classes that are marked as Variant as those require an MI to pass to
SubTargetInfo::resolveSchedClass.

Dispose the codegen even when just writing the bitcode file.

This makes it possible to add timers to the code generator and still use them

Remove wild .debug_aranges entries generated from unimportant labels

r191052 added emitting .debug_aranges to Clang, but this
functionality is broken: it uses all MC labels added in DWARF Asm
printer, including the labels for build relocations between
different DWARF sections, like .Lsection_line or .Ldebug_loc0.

As a result, if any DIE .debug_info would contain "DW_AT_location=0x123"
attribute, .debug_aranges would also contain a range starting from 0x123,
breaking tools that rely on this section.

This patch fixes this by using only MC labels that corresponds to the
addresses in the user program.

CaptureTracking: Plug a loophole in the "too many uses" heuristic.

The heuristic was added to avoid spending too much compile time A specially
crafted test case (PR17461, PR16474) with many uses on a select or bitcast
instruction can still trigger the slow case. Add a check for that case.

This only affects compile time, don't have a good way to test it.

Added checking code whehter target supports specific dag combining about rotate
or not. The corresponding dag patterns are as following:

"DAGCombier::MatchRotate" function in DAGCombiner.cpp
Pattern1
// fold (or (shl (*ext x), (*ext y)),
//          (srl (*ext x), (*ext (sub 32, y)))) ->
//   (*ext (rotl x, y))
// fold (or (shl (*ext x), (*ext y)),
//          (srl (*ext x), (*ext (sub 32, y)))) ->
//   (*ext (rotr x, (sub 32, y)))

pattern2
// fold (or (shl (*ext x), (*ext (sub 32, y))),
//          (srl (*ext x), (*ext y))) ->
//   (*ext (rotl x, y))
// fold (or (shl (*ext x), (*ext (sub 32, y))),
//          (srl (*ext x), (*ext y))) ->
//   (*ext (rotr x, (sub 32, y)))

[llvm-c][Disassembler] When printing latency information, fall back to the
