Factorize macro definition code in macrotab.c
When first fixing splay tree key leaks in macrotab.c, some duplicated code
logic was factorized.
The key leaks will be fixed in libiberty, but the code factorization
is better kept in any case.

2019-02-06 Philippe Waroquiers <philippe.waroquiers@skynet.be>
* macrotab.c (macro_define_internal): New function that
factorizes macro_define_object_internal and macro_define_function
code.
(macro_define_object_internal): Use macro_define_internal.
(macro_define_function): Likewise.
