PATCH: Fix Tru64 UNIX bootstrap

[Rainer Orth]

As of rev 147380, mainline didn't bootstrap on alpha-dec-osf[45]:

gcc/config/alpha/alpha.c: In function 'alpha_initialize_trampoline':
gcc/config/alpha/alpha.c:5500: error: enum conversion when passing argument 2 of 'emit_library_call' is invalid in C++
gcc/rtl.h:2267: note: expected 'enum libcall_type' but argument is of type 'int'

gcc/mips-tfile.c:3671: warning: enum conversion in assignment is invalid in C++
gcc/mips-tfile.c:3672: warning: enum conversion in assignment is invalid in C++

gcc/mips-tdump.c: In function 'print_file_desc':
gcc/mips-tdump.c:1119: error: enum conversion when passing argument 1 of 'glevel_to_string' is invalid in C++
gcc/mips-tdump.c:408: note: expected 'glevel_t' but argument is of type 'unsigned char:2'

The following trivial patch fixes this and allows the bootstrap to
continue; currently the testsuite is running.

I think it qualifies as obvious, and since mips-t* are only used by the
alpha-dec-osf port, I can check those in on my own.

I'll check it in within a day unless someone objects.
