When the result of an EXTRACT_SUBREG, INSERT_SUBREG, or SUBREG_TO_REG 

operator is used by a CopyToReg to export the value to a different
block, don't reuse the CopyToReg's register for the subreg operation
result if the register isn't precisely the right class for the
subreg operation.

Also, rename the h-registers.ll test, now that there are more
than one.
