Add support for the v1i64 type. This makes better code for this:
...
#include <mmintrin.h>
extern __m64 C;
void baz(__v2si *A, __v2si *B)
{
*A = C;
_mm_empty();
}
We get this:
_baz:
call "L1$pb"
"L1$pb":
popl %eax
movl L_C$non_lazy_ptr-"L1$pb"(%eax), %eax
movq (%eax), %mm0
movl 4(%esp), %eax
movq %mm0, (%eax)
emms
ret
GCC gives us this:
_baz:
pushl %ebx
call L3
"L00000000001$pb":
L3:
popl %ebx
subl $8, %esp
movl L_C$non_lazy_ptr-"L00000000001$pb"(%ebx), %eax
movl (%eax), %edx
movl 4(%eax), %ecx
movl 16(%esp), %eax
movl %edx, (%eax)
movl %ecx, 4(%eax)

Two changes:
...
1) codegen a shift of a register as a shift, not an LEA.
2) teach the RA to convert a shift to an LEA instruction if it wants something
in three-address form.
This gives us asm diffs like:
- leal (,%eax,4), %eax
+ shll $2, %eax
which is faster on some processors and smaller on all of them.
and, more interestingly:
- movl 24(%esi), %eax
- leal (,%eax,4), %edi
+ movl 24(%esi), %edi
+ shll $2, %edi
Without #2 , #1 was a significant pessimization in some cases.
This implements CodeGen/X86/shift-codegen.ll

in X86-64 CCC, i8/i16 arguments are already properly zext/sext'd on input.

int test(short X) { return (int)X; }
to:

_test:
