        src/usr.bin/xlint/lint1: cgram.y

Log Message:
lint: only allow GCC attribute in null statement

The only indented usage in that position is a fallthrough statement, as
a replacement for a /* FALLTHROUGH */ comment.  There is no point in
using _Noreturn or _Alignas as a statement.

Ideally, instead of gcc_attribute, the grammar would allow
gcc_attribute_list here (as always with GCC attributes), but that would
have introduced a reduce/reduce conflict, due to the attributes in the
middle of labeled_statement.
