ARM64: Use the shifter operands.
This introduces architecture-specific instruction simplification.
On ARM64 we try to merge shifts and sign-extension operations into
arithmetic and logical instructions.
For example for the Java code
int res = a + (b << 5);
we would generate
lsl w3, w2, #5
add w0, w1, w3
and we now generate
add w0, w1, w2, lsl #5
