X86 MC: Handle instructions like fxsave that match multiple operand sizes
Instructions like 'fxsave' and control flow instructions like 'jne'
match any operand size. The loop I added to the Intel syntax matcher
assumed that using a different size would give a different instruction.
Now it handles the case where we get the same instruction for different
memory operand sizes.
This also allows us to remove the hack we had for unsized absolute
memory operands, because we can successfully match things like 'jnz'
without reporting ambiguity. Removing this hack uncovered test case
involving 'fadd' that was ambiguous. The memory operand could have been
single or double precision.

[SDAG] Re-instate r215611 with a fix to a pesky X86 DAG combine.
This combine is essentially combining target-specific nodes back into target
independent nodes that it "knows" will be combined yet again by a target
independent DAG combine into a different set of target-independent nodes that
are legal (not custom though!) and thus "ok". This seems... deeply flawed. The
crux of the problem is that we don't combine un-legalized shuffles that are
introduced by legalizing other operations, and thus we don't see a very
profitable combine opportunity. So the backend just forces the input to that
combine to re-appear.
However, for this to work, the conditions detected to re-form the unlegalized
nodes must be *exactly* right. Previously, failing this would have caused poor
code (if you're lucky) or a crasher when we failed to select instructions.
After r215611 we would fall back into the legalizer. In some cases, this just
"fixed" the crasher by produces bad code. But in the test case added it caused
the legalizer and the dag combiner to iterate forever.
The fix is to make the alignment checking in the x86 side of things match the
alignment checking in the generic DAG combine exactly. This isn't really a
satisfying or principled fix, but it at least make the code work as intended.
It also highlights that it would be nice to detect the availability of under
aligned loads for a given type rather than bailing on this optimization. I've
left a FIXME to document this.
Original commit message for r215611 which covers the rest of the chang:
[SDAG] Fix a case where we would iteratively legalize a node during
combining by replacing it with something else but not re-process the
node afterward to remove it.
In a truly remarkable stroke of bad luck, this would (in the test case
attached) end up getting some other node combined into it without ever
getting re-processed. By adding it back on to the worklist, in addition
to deleting the dead nodes more quickly we also ensure that if it
*stops* being dead for any reason it makes it back through the
legalizer. Without this, the test case will end up failing during
instruction selection due to an and node with a type we don't have an
instruction pattern for.
It took many million runs of the shuffle fuzz tester to find this.

MC: Split the x86 asm matcher implementations by dialect
The existing matcher has lots of AT&T assembly dialect assumptions baked
into it. In particular, the hack for resolving the size of a memory
operand by appending the four most common suffixes doesn't work at all.
The Intel assembly dialect mnemonic table has ambiguous entries, so we
need to try matching multiple times with different operand sizes, since
that's the only way to choose different instruction variants.
This makes us more compatible with gas's implementation of Intel
assembly syntax. MSVC assumes you want byte-sized operations for the
instructions that we reject as ambiguous.

There is no functionality change here except in the way we assemble and

ArgPromotion: Don't touch variadic functions
Adding, removing, or changing non-pack parameters can change the ABI
classification of pack parameters. Clang and other frontends encode the
classification in the IR of the call site, but the callee side
determines it dynamically based on the number of registers consumed so
far. Changing the prototype affects the number of registers consumed
would break such code.
Dead argument elimination performs a similar task and already has a
similar check to avoid this problem.
