Duncan P. N. Exon Smith ad98745561 MC: Constify MCSubtargetInfo in getDeprecationInfo(), NFC
There's no reason to be able to mutate `MCSubtargetInfo` in
`getDeprecationInfo()`.  Constify the reference.

Michael Kuperstein db0712f986 Use std::bitset for SubtargetFeatures.
Previously, subtarget features were a bitfield with the underlying type being uint64_t. 
Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset.
No functional change.

The first several times this was committed (e.g. r229831, r233055), it caused several buildbot failures.
Apparently the reason for most failures was both clang and gcc's inability to deal with large numbers (> 10K) of bitset constructor calls in tablegen-generated initializers of instruction info tables. 
This should now be fixed.

Pete Cooper 80735a2d8e Move some methods to a new MCInstrDesc.cpp file to allow includes to be trimmed. NFC.
MCInstrDesc.h includes things like MCInst.h which i can now remove after this.  That will be a future commit.
