libgccjit.h: Uncomment macro definition for testing gcc_jit_context_new_bitcast support
(cherry-picked from r13-2004-g9385cd9c74cf66)
The macro definition for LIBGCCJIT_HAVE_gcc_jit_context_new_bitcast
was earlier located in the documentation comment for
gcc_jit_context_new_bitcast, making it unavailable to code that
consumed libgccjit.h. This commit moves the definition out of the
comment, making it effective.
gcc/jit/ChangeLog:
* libgccjit.h (LIBGCCJIT_HAVE_gcc_jit_context_new_bitcast): Move
definition out of comment.
