Just a quick warning, we're now specified that the MacroAssembler shift methods
must clamp the shift amount to the range 0..31 - see
http://trac.webkit.org/changeset/50595 .

On x86 this requires no additional code, since the operand to the shift is
implicitly clamped to this range.  On the ARM platforms we plant an extra arm
instruction – I don't know what the specified behaviour is on MIPS, you may
need to do the same?
