Improve code generation of long shifts by 32.
On this testcase:
long %test(long %X) {
%Y = shr long %X, ubyte 32
ret long %Y
}
instead of:
t:
mov %EAX, DWORD PTR [%ESP + 4]
mov %EAX, DWORD PTR [%ESP + 8]
sar %EAX, 0
mov %EDX, 0
ret
we now emit:
test:
mov %EAX, DWORD PTR [%ESP + 4]
mov %EAX, DWORD PTR [%ESP + 8]
mov %EDX, 0
ret
