teach the x86 address matching stuff to handle

(shl (or x,c), 3) the same as (shl (add x, c), 3)
when x doesn't have any bits from c set.
This finishes off PR1135. Before we compiled the block to:
to:
LBB0_3: ## %bb
cmpb $4, %dl
sete %dl
addb %dl, %cl
movb %cl, %dl
shlb $2, %dl
addb %r8b, %dl
shlb $2, %dl
movzbl %dl, %edx
movl %esi, (%rdi,%rdx,4)
leaq 2(%rdx), %r9
movl %esi, (%rdi,%r9,4)
leaq 1(%rdx), %r9
movl %esi, (%rdi,%r9,4)
addq $3, %rdx
movl %esi, (%rdi,%rdx,4)
incb %r8b
decb %al
movb %r8b, %dl
jne LBB0_1
Now we produce:
LBB0_3: ## %bb
cmpb $4, %dl
sete %dl
addb %dl, %cl
movb %cl, %dl
shlb $2, %dl
addb %r8b, %dl

movzbl %dl, %edx
movl %esi, (%rdi,%rdx,4)
movl %esi, 8(%rdi,%rdx,4)
movl %esi, 4(%rdi,%rdx,4)
movl %esi, 12(%rdi,%rdx,4)

Because of the EMMS problem, right now we have to support
...
user-defined operations that use MMX register types, but
the compiler shouldn't generate them on its own. This adds
a Synthesizable abstraction to represent this, and changes
the vector widening computation so it won't produce MMX types.
(The motivation is to remove noise from the ABI compatibility
part of the gcc test suite, which has some breakage right now.)
