x86: Update 'P' operand modifier for -fno-plt

Update 'P' operand modifier for -fno-plt to support inline assembly
statements.  In 64-bit, we can always load function address with
@GOTPCREL.  In 32-bit, we load function address with @GOT only for
non-PIC since PIC register may not be available at call site.
