fixed physical registers. Start moving fp comparison
aliases to the .td file (which default to using %st1 if
nothing is specified).

result instruction operand numbering matched the result pattern.
Fixing this allows us to move the xchg/test aliases to the .td file.

operand list instead of the operand list redundantly declared on the alias
or instruction.
With this change, we finally remove the ins/outs list on the alias. Before:
def : InstAlias<(outs GR16:$dst), (ins GR8 :$src),
"movsx $src, $dst",
(MOVSX16rr8W GR16:$dst, GR8:$src)>;
After:
def : InstAlias<"movsx $src, $dst",
(MOVSX16rr8W GR16:$dst, GR8:$src)>;
This also makes the alias mechanism more general and powerful, which will
be exploited in subsequent patches.

(someinst GR16:$foo, GR32:$foo)
Reimplement BuildAliasOperandReference to be correctly
based on the names of operands in the result pattern,
instead of on the instruction operand definitions.

and as such can be represented by an MVT - the more complicated
EVT is not needed. Use MVT for ValVT everywhere.

Right now the code is partitioned but the behavior is the same.
This should be improved in the near future. This removes some
uses of TheOperandList.

now matchables contain an explicit list of how to populate each
operand in the result instruction instead of having them somehow
magically be correlated to the input inst.

value type, so there is no point in passing it around using
an EVT. Use the simpler MVT everywhere. Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.

ins/outs list that isn't specified by their asmstring. Previously
the asmmatcher would just force a 0 register into it, which clearly
isn't right. Mark a bunch of ARM instructions that use this as
isCodeGenOnly. Some of them are clearly pseudo instructions (like
t2TBB) others use a weird hasExtraSrcRegAllocReq thing that will
either need to be removed or the asmmatcher will need to be taught
about it (someday).

filling them in one at a time. Previously this iterated over the
asmoperands, which left the problem of "holes". The new approach
simplifies things.

merging it into a Token field in Operand, and moving the first
token to an explicit mnemonic field. These were parallel
arrays before (except for the mnemonic) which kept confusing me.

aliases installed and working. They now work when the
matched pattern and the result instruction have exactly
the same operand list.
This is now enough for us to define proper aliases for
movzx and movsx, implementing rdar://8017633 and PR7459.
Note that we do not accept instructions like:
movzx 0(%rsp), %rsi
GAS accepts this instruction, but it doesn't make any
sense because we don't know the size of the memory
operand. It could be 8/16/32 bits.

isAssemblerInstruction -> Validate since that is what
it does (modulo the ARM $lane hack).

If these comments are important, the instlowering stuff can print them.

argument passing. Consolidate all SingletonRegister detection
and handling into a new
InstructionInfo::getSingletonRegisterForToken method instead of
having it scattered about. No change in generated .inc files.

CodeGenInstruction::FlattenAsmStringVariants method. Use it
to simplify the code in AsmWriterInst, which now no longer
needs to worry about variants.
