perf parse-regs: Split parse_regs
The available registers for --int-regs and --user-regs may be different,
e.g. XMM registers.
Split parse_regs into two dedicated functions for --int-regs and
--user-regs respectively.
Modify the warning message. "--user-regs=?" should be applied to show
the available registers for --user-regs.
