f36c3de849 [Disasm][AVX512] Implement decoding of top bit for non-destructive reg fields 
V' bit in the P2 byte of the EVEX prefix provides the top bit of the NDD and
NDS register fields.  This was simply not used in the decoder until now.

Fixes <rdar://problem/17402661>

856361cb06 Support: Move class ScaledNumber 
ScaledNumber has been cleaned up enough to pull out of BFI now.  Still
work to do there (tests for shifting, bloated printing code, etc.), but
it seems clean enough for its new home.

This makes the buffer ownership on error conditions very natural. The buffer
is only moved out of the argument if an object is constructed that now
owns the buffer.

20732d55c2 [FastISel][X86] Lower unsupported selects to control-flow. 
The extends the select lowering coverage by emiting pseudo cmov
instructions. These insturction will be later on lowered to control-flow to
simulate the select.

d0976a3d20 [FastISel][X86] Add support for floating-point select. 
This extends the select lowering to support floating-point selects. The
lowering depends on SSE instructions and that the conditon comes from a
floating-point compare. Under this conditions it is possible to emit an
optimized instruction sequence that doesn't require any branches to
simulate the select.

1f659329b6 Make ObjectFile and BitcodeReader always own the MemoryBuffer. 
This allows us to just use a std::unique_ptr to store the pointer to the buffer.
The flip side is that they have to support releasing the buffer back to the
caller.

Overall this looks like a more efficient and less brittle api.

3cffac5061 Fix PR20056: Implement pseudo LDR <reg>, =<literal/label> for AArch64 
This patch is based on the changes from ARM target [1,2]

Based on ARM doc [3], if the literal value can be loaded with a valid MOV,
it can emit that instruction. This is implemented in this patch.

Tweak test cases that used llvm-nm with standard input to add a "-" to
indicate that and add a test case to check the default of a.out for llvm-nm.

9dd6fee485 Recommit 211309 (StringMap::insert), reverted in 211328 due to issues with private, but non-deleted, move members. 
Certain versions of GCC (~4.7) couldn't handle the SFINAE on access
control, but with "= delete" (hidden behind a macro for portability)
this issue is worked around/addressed.
