i386: Replace internal_function attribute for __mcount_internal

Browse Source 
__mcount_internal is called from assembler code.  Use an explicit
regparm attribute to pass both arguments in registers, to match what
used to happen with internal_function before commit
fbdc1e3e8d (i386: Do not set
internal_function).
