[PATCH] go-lang.c: remove a redundant cast

[David Malcolm]

Amongst many other changes, r146451 added this cast:

 -#define GET_MODE_CLASS(MODE)  mode_class[MODE]
 +#define GET_MODE_CLASS(MODE)  ((enum mode_class) mode_class[MODE])

making a cast in go-lang.c redundant; remove it.

Successfully bootstrapped&regrtested on x86_64-pc-linux-gnu.

OK for trunk?

gcc/go/ChangeLog:
        * go-lang.c (go_langhook_type_for_mode): Remove redundant cast
        from result of GET_MODE_CLASS.  Minor formatting fixes.
