Jakob Stoklund Olesen add0c43ebb Give targets a chance to expand even standard pseudos. ...

Allow targets to expand COPY and other standard pseudo-instructions
before they are expanded with copyPhysReg().

This allows the target to examine the COPY instruction for extra
operands indicating it can be widened to a preferable super-register
copy.  See the ARM -widen-vmovs option.
