* infrun.c (handle_inferior_event): Move the check for return
trampolines ahead of the check for function trampolines.
* mips-tdep.h (MIPS_S2_REGNUM, MIPS_GP_REGNUM): New macros.
* mips-tdep.c (mips_str_mips16_call_stub): New variable.
(mips_str_mips16_ret_stub): Likewise.
(mips_str_call_fp_stub): Likewise.
(mips_str_call_stub): Likewise.
(mips_str_fn_stub): Likewise.
(mips_str_pic): Likewise.
(mips_in_frame_stub): New function.
(mips_unwind_pc): Return the return address rather than the PC
if the PC of an intermediate frame is inside a call thunk.
(mips_is_stub_suffix): New function.
(mips_is_stub_mode): Likewise.
(mips_get_mips16_fn_stub_pc): Likewise.
(mips_skip_mips16_trampoline_code): Update to handle all the
currently generated stub types. Don't recurse into __fn_stub
thunks. Remove heuristics to handle stubs beyond etext/_etext.
Use cooked register accesses.
(mips_in_return_stub): Reintroduce function.
(mips_skip_trampoline_code): Traverse trampolines recursively.
(mips_gdbarch_init): Handle MIPS16 return trampolines.
