Reimplement BuildResultOperands to be in terms of the result instruction's
...
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.

Implement enough of the missing instalias support to get

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.

fix a subtle bug I introduced in my refactoring, where we stopped preferring
...
the i8 versions of instructions in some cases. In test6, we started
generating:
cmpq $0, -8(%rsp) ## encoding: [0x48,0x81,0x7c,0x24,0xf8,0x00,0x00,0x00,0x00]
## <MCInst #478 CMP64mi32

## <MCOperand Imm:1>
## <MCOperand Reg:0>
## <MCOperand Imm:-8>
## <MCOperand Reg:0>
## <MCOperand Imm:0>>
instead of:
cmpq $0, -8(%rsp) ## encoding: [0x48,0x83,0x7c,0x24,0xf8,0x00]
## <MCInst #479 CMP64mi8

## <MCOperand Reg:0>
## <MCOperand Imm:-8>

Reimplement (part of) the or -> add optimization. Matching 'or' into 'add'
...
is general goodness because it allows ORs to be converted to LEA to avoid
inserting copies. However, this is bad because it makes the generated .s
file less obvious and gives valgrind heartburn (tons of false positives in
bitfield code).
While the general fix should be in valgrind, we can at least try to avoid
emitting ADD instructions that *don't* get promoted to LEA. This is more
work because it requires introducing pseudo instructions to represents
"add that knows the bits are disjoint", but hey, people really love valgrind.
This fixes this testcase:

Massive rewrite of MMX:
...
The x86_mmx type is used for MMX intrinsics, parameters and
return values where these use MMX registers, and is also
supported in load, store, and bitcast.
Only the above operations generate MMX instructions, and optimizations
do not operate on or produce MMX intrinsics.
MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into
smaller pieces. Optimizations may occur on these forms and the
result casted back to x86_mmx, provided the result feeds into a
previous existing x86_mmx operation.
The point of all this is prevent optimizations from introducing
MMX operations, which is unsafe due to the EMMS problem.
