* blockframe.c (find_pc_partial_function): mst_file_text
symbols do not live in the shared library transfer table.
* ch-exp.y (decode_integer_value, match_character_literal,
match_bitstring_literal): Guard tolower calls with isupper,
tolower on old BSD systems blindly subtracts a constant.

Only change here is that create_new_frame would no longer init extra
frame info; SETUP_ARBITRARY_FRAME would have to do that.
INIT_PREV_FRAME(fromleaf, prev)
Replace INIT_EXTRA_FRAME_INFO and INIT_FRAME_PC.
Replace INIT_EXTRA_FRAME_INFO and INIT_FRAME_PC. This should
also return a flag saying whether to keep the new frame, or
whether to discard it, because on some machines (e.g. mips) it
is really awkward to have FRAME_CHAIN_VALID called *before*
INIT_EXTRA_FRAME_INFO (there is no good way to get information
deduced in FRAME_CHAIN_VALID into the extra fields of the new frame).
std_frame_pc(fromleaf, prev)
This is the default setting for INIT_PREV_FRAME. It just does what
the default INIT_FRAME_PC does. Some machines will call it from
INIT_PREV_FRAME (either at the beginning, the end, or in the middle).
Some machines won't use it.
