Remove unused variables
This patch removes set-but-unused variables. This holds all the
removals I consider to be simple and relatively uncontroversial.
2016-07-14 Tom Tromey <tom@tromey.com>
* mips-tdep.c (micromips_scan_prologue): Remove "frame_addr".
(mips_o32_push_dummy_call): Remove "stack_used_p".
* aarch64-tdep.c (aarch64_record_data_proc_imm): Remove
"insn_bit28".
* rust-lang.c (rust_print_type): Remove "len".
* rust-exp.y (super_name): Remove "current_len".
* python/py-framefilter.c (py_print_type): Remove "type".
* mdebugread.c (parse_partial_symbols): Remove
"past_first_source_file".
<N_SO>: Remove "valu", "first_so_symnum", "prev_textlow_not_set".
* m2-valprint.c (m2_print_unbounded_array): Remove
"content_type".
(m2_val_print): Remove "i".
* linespec.c (unexpected_linespec_error): Remove "cleanup".
* f-valprint.c (f_val_print): Remove "i".
* elfread.c (elf_symtab_read): Remove "offset".
* dwarf2-frame.c (dwarf2_fetch_cfa_info): Remove "addr_size".
* jit.c (jit_dealloc_cache): Remove "i" and "frame_arch".
