Replace rotate patterns and invokes with HRor IR.
Replace constant and register version bitfield rotate patterns, and
rotateRight/Left intrinsic invokes, with new HRor IR.
Where k is constant and r is a register, with the UShr and Shl on
either side of a |, +, or ^, the following patterns are replaced:
x >>> #k OP x << #(reg_size - k)
x >>> #k OP x << #-k
x >>> r OP x << (#reg_size - r)
x >>> (#reg_size - r) OP x << r
x >>> r OP x << -r
x >>> -r OP x << r
Implemented for ARM/ARM64 & X86/X86_64.
Tests changed to not be inlined to prevent optimization from folding
them out. Additional tests added for constant rotate amounts.
