Various patterns use "register_operand" "l" (or "=l") although those
patterns are only created refering to LR_REGNO directly. This patch
changes those patterns to use the hard regs as well.
Bootstrapped and regression checked on powerpc64-linux -m32,-m64.

directly instead of via the "l" constraint. Renumber operands.
Fix whitespace.
