* mips-tdep.c (mips_in_call_stub, mips_in_return_stub,
mips_skip_stub, mips_ignore_helper): New functions for dealing
with MIPS16 call/return thunks.
(mips_init_frame_pc_first): New function to implement
INIT_FRAME_PC_FIRST macro; includes code from old macro plus
new code to skip over MIPS16 thunks.
(mips_frame_chain): Skip over MIPS16 thunks.
* config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
mips_skip_stub, mips_ignore_helper): Declare.
(IN_SOLIB_CALL_TRAMPOLINE, IN_SOLIB_RETURN_TRAMPOLINE,
SKIP_TRAMPOLINE_CODE, IGNORE_HELPER_CALL): New macros that invoke
the above functions.
(INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
(mips_init_frame_pc): Declare.
* infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
to decide if certain library function calls should be ignored.
