3e55612472 First part of refactoring ARM addrmode2 (load/store) instructions to be more
explicit about the operands. Split out the different variants into separate
instructions. This gives us the ability to, among other things, assign
different scheduling itineraries to the variants. rdar://8477752.

46f55527d8 Generalize tblgen's dag parsing logic to handle arbitrary expressions
as the operator of the dag.  Specifically, this allows parsing things
like (F.x 4) in addition to just (a 4).

Unfortunately, this runs afoul of an idiom being used by llvmc.  It
is using dags like (foo [1,2,3]) to represent a list of stuff being
passed into foo.  With this change, this is parsed as a [1,2,3] 
subscript on foo instead of being the first argument to the dag.
Cope with this in the short term by requiring a "-llvmc-temp-hack"
argument to tblgen to get the old parsing behavior.

0488fb649a 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.

52a261b3c1 fix a long standing wart: all the ComplexPattern's were being
passed the root of the match, even though only a few patterns
actually needed this (one in X86, several in ARM [which should
be refactored anyway], and some in CellSPU that I don't feel 
like detangling).   Instead of requiring all ComplexPatterns to
take the dead root, have targets opt into getting the root by
putting SDNPWantRoot on the ComplexPattern.

instruction in the class would be decoded to. Or zero if the number of
uOPs must be determined dynamically.

This will be used to determine the cost-effectiveness of predicating a
micro-coded instruction.

9bb9fa19a5 generalize my previous operand loc info hack. If the same operand
is busted for all variants, report it as the location.  This allows
us to get the operand right for bugs like:

t.s:3:12: error: invalid operand for instruction
	outb %al, %gs
	          ^

Even though there are reg/imm and reg/reg forms of this instruction.

ce4a3355d9 in the case where an instruction only has one implementation
of a mneumonic, report operand errors with better location
info.  For example, we now report:

t.s:6:14: error: invalid operand for instruction
        cwtl $1
             ^

but we fail for common cases like:

t.s:11:4: error: invalid operand for instruction
   addl $1, $1
   ^

because we don't know if this is supposed to be the reg/imm or imm/reg
form.

a008e8ac73 Now that we know if we had a total fail on the instruction mnemonic,
give a more detailed error.  Before:

t.s:11:4: error: unrecognized instruction
   addl $1, $1
   ^
t.s:12:4: error: unrecognized instruction
   f2efqefa $1
   ^

After:

t.s:11:4: error: invalid operand for instruction
   addl $1, $1
   ^
t.s:12:4: error: invalid instruction mnemonic 'f2efqefa'
   f2efqefa $1
   ^

This fixes rdar://8017912 - llvm-mc says "unrecognized instruction" when it means "invalid operands"

e206fcf0e9 special case the mnemonic operand of the instruction in the
generated matcher, emiting it as a column in the MatchEntry
table instead of forcing it to go through classification and
everything else.  Making it be classified caused tblgen to
produce a ton of one-off classes for each mneumonic.  This
should reduce the size of the generated matcher significantly
while paving the way for future improvements.

ec6789f4f9 have tblgen detect when an instruction would have matched, but
failed because a subtarget feature was not enabled.  Use this to
remove a bunch of hacks from the X86AsmParser for rejecting things
like popfl in 64-bit mode.  Previously these hacks weren't needed,
but were important to get a message better than "invalid instruction"
when used in the wrong mode.

This also fixes bugs where pushal would not be rejected correctly in
32-bit mode (just pusha).
