Ranjeet Singh 86ecbb7b54 Reverting r241058 because it's causing buildbot failures.

Ranjeet Singh 5b119091a1 There are a few places where subtarget features are still
represented by uint64_t, this patch replaces these
usages with the FeatureBitset (std::bitset) type.

James Y Knight f90346f8f6 [SPARC] Repair GOT references to internal symbols.
They had been getting emitted as a section + offset reference, which
is bogus since the value needs to be the offset within the GOT, not
the actual address of the symbol's object.

Daniel Sanders a73f1fdb19 Replace string GNU Triples with llvm::Triple in MCSubtargetInfo and create*MCSubtargetInfo(). NFC.
Summary:
This continues the patch series to eliminate StringRef forms of GNU triples
from the internals of LLVM that began in r239036.

James Y Knight c49e78851c Sparc: support the "set" synthetic instruction.
This pseudo-instruction expands into 'sethi' and 'or' instructions,
or, just one of them, if the other isn't necessary for a given value.

James Y Knight 24060be73a Sparc: Add the "alternate address space" load/store instructions.
- Adds support for the asm syntax, which has an immediate integer
  "ASI" (address space identifier) appearing after an address, before
  a comma.

- Adds the various-width load, store, and swap in alternate address
  space instructions. (ldsba, ldsha, lduba, lduha, lda, stba, stha,
  sta, swapa)

This does not attempt to hook these instructions up to pointer address
spaces in LLVM, although that would probably be a reasonable thing to
do in the future.

James Y Knight 807563df22 Add support for the Sparc implementation-defined "ASR" registers.
(Note that register "Y" is essentially just ASR0).

Also added some test cases for divide and multiply, which had none before.

James Y Knight c09bdfa4cb Sparc: Prefer reg+reg address encoding when only one register used.
Reg+%g0 is preferred to Reg+imm0 by the manual, and is what GCC produces.

Futhermore, reg+imm is invalid for the (not yet supported) "alternate
address space" instructions.

Craig Topper 589ceee7f4 Minor cleanup to all the switches after MatchInstructionImpl in all the AsmParsers.
Make sure they all have llvm_unreachable on the default path out of the switch. Remove unnecessary "default: break". Remove a 'return' after unreachable. Fix some indentation.

Tim Northover 26bb14e6a7 TableGen: allow use of uint64_t for available features mask.
ARM in particular is getting dangerously close to exceeding 32 bits worth of
possible subtarget features. When this happens, various parts of MC start to
fail inexplicably as masks get truncated to "unsigned".

Mostly just refactoring at present, and there's probably no way to test.

David Blaikie 960ea3f018 AsmMatchers: Use unique_ptr to manage ownership of MCParsedAsmOperand
I saw at least a memory leak or two from inspection (on probably
untested error paths) and r206991, which was the original inspiration
for this change.

I ran this idea by Jim Grosbach a few weeks ago & he was OK with it.
Since it's a basically mechanical patch that seemed sufficient - usual
post-commit review, revert, etc, as needed.
