daily update

Add proper handling for internal functions and STT_GNU_IFUNC symbols in Ada mode.

The code for handling calls to internal functions (esp., Python
functions) and for handling STT_GNU_IFUNC had not been added to the Ada
expression evaluator.  This change adapts them from eval.c.

gdb/Changelog:

        * ada-lang.c (ada_evaluate_subexp): Add cases for
          TYPE_CODE_INTERNAL_FUNCTION and for TYPE_GNU_IFUNC, following
          their treatment in eval.c.

Handle sparc compare-and-branch

SPARC-T4 adds a "compare and branch" instruction which fuses
a compare and a branch instruction into one.  The branch
is non-delayed, there are no anulling facilities, and the
displacement is 10-bits.

This also corrects the existing bit test for Branch on
Integer Register.  The distinguising characteristic between
Branch on Integer Register and Compare-and-Branch is bit
28.  The existing code was checking bit 24 for zero, but
that's pointless because bit 24 is already covered by
the "X_OP2 (insn) == 3" test.
