Hot/cold partitioning update patch. The problems that this patch
attemptd to address/fix are:
- Fix places where adding in_unlikely_executed_text to the enum data
type "in_section" threw off switch case statements.
- Make it work correctly (by turning it off) for functions where user
specifies "__attribute__ section"
- Make it work correctly (by turning it off) for linkonce sections
- Make it work correctly with -ffunction-sections flag
- Make it output correct cold section labels
- Undo some changes to original assembly code generation
- Turn off hot/cold partitioning in the presence of DWARF debugging (for
the moment)
- Turn off hot/cold partitioning for architectures that do not support
named sections
- Use variables rather than constants for cold section labels and names (to
work correctly with -ffunction-sections, among other things)

function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.

foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
