* gprof.c (default_excluded_list): Add "__mcount".
* gprof.c (main): Change ifdef __osf__ to __alpha__.
* gmon_io.c (gmon_out_read): If BSD44_FORMAT is defined, get the
profiling rate from the header.
* gmon.h (struct raw_phdr): Only include pad if both __alpha__ and
__osf__ are defined. Add new fields if BSD44_FORMAT is defined.
* alpha.h (MIN_INSN_SIZE): Define.
* core.c (MIN_INSN_SIZE): If not defined, define as 1.
(core_sym_class): Ignore debugging symbols.
(core_create_line_syms): Use MIN_INSN_SIZE when gathering line
information.
