RDPID instruction outputs to a word-sized register (64-bit on x86_64 and
32-bit on x86_32). Use an unsigned long variable to store the correct size.
LSL outputs to 32-bit register, use %k operand prefix to always print the
32-bit name of the register.
Use RDPID insn mnemonic while at it as the minimum binutils version of
2.30 supports it.
[ bp: Merge two patches touching the same function into a single one. ]
