ccafe05df1 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.

ee058202fa 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.

f272788a95 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.

0e13ba8208 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.

a9a94ce839 TableGen: fix operand counting for aliases 
TableGen has a fairly dubious heuristic to decide whether an alias should be
printed: does the alias have lest operands than the real instruction. This is
bad enough (particularly with no way to override it), but it should at least be
calculated consistently for both strings.

This patch implements that logic: first get the *correct* string for the
variant, in the same way as the Matcher, without guessing; then count the
number of whitespace chars.

There are basically 4 changes this brings about after the previous
commits; all of these appear to be good, so I have changed the tests:

+ ARM64: we print "neg X, Y" instead of "sub X, xzr, Y".
+ ARM64: we skip implicit "uxtx" and "uxtw" modifiers.
+ Sparc: we print "mov A, B" instead of "or %g0, A, B".
+ Sparc: we print "fcmpX A, B" instead of "fcmpX %fcc0, A, B"
