one method declaration.
(getURLStreamHandler): Added documentation from classpath.
From-SVN: r69606
(push_label_level, pop_label_level): Kill.
(struct binding_level): Rename level_chain to outer.
Add outer_function field. Change parm_flag, function_body,
keep, keep_if_subblocks to 1-bit bitfields of type bool.
(current_function_level): New variable.
(keep_next_level_flag, keep_next_if_subblocks): Change type to bool.
(keep_next_level, declare_parm_level, warn_if_shadowing):
Update to match.
(struct language_function): Kill named_labels, shadowed_labels fields.
(c_init_decl_processing, start_function, c_push__function_context)
(c_pop_function_context): No need to muck with named_labels nor
shadowed_labels.
(make_binding_level): No need to clear the structure here.
(pop_binding_level): Always operate on current_binding_level.
Update current_function_level if necessary.
(pushlevel): Don't clear named_labels. Update current_function_level
if necessary. Use "true" and "false" where appropriate.
(poplevel): Diagnose labels defined but not used, or vice
versa, and clear out label-meanings leaving scope, while
walking down the decls list, for all binding levels.
Handle LABEL_DECLs appearing in the shadowed list.
pop_binding_level takes no arguments.
(pushdecl_function_level): Use current_function_level.
(make_label, bind_label): New static functions.
(declare_label): New exported function.
(lookup_label, define_label): Rewritten for new data structure.
(shadow_label): Kill.
* c-tree.h: Prototype declare_label; don't prototype
push_label_level, pop_label_level, nor shadow_label.
* c-parse.in: Remove all calls to push_label_level and
pop_label_level. Use declare_label for __label__ decls.
* doc/extend.texi: Clarify that __label__ can be used to
declare labels with local scope in any nested block, not
just statement expressions. Cross-reference nested functions
section from local labels section.
testsuite:
* gcc.dg/noncompile/label-1.c: New comprehensive test case for
diagnostics of ill-formed constructs involving labels.
* gcc.dg/noncompile/label-lineno-1.c: Add error regexp for
the new 'previously defined here' message.

* fold-const.c (const_binop): Avoid performing the FP operation at
compile-time, if either operand is NaN and we honor signaling NaNs,
or if we're dividing by zero and either flag_trapping_math is set
or the desired mode doesn't support infinities.

potential run-time exceptions or traps.
* tree.h (fold_initializer): Prototype here.
* c-typeck.c (build_binary_op): Move to the end of the file so
that intializer_stack is in scope. If constructing an initializer,
i.e. when initializer_stack is not NULL, use fold_initializer to
fold expressions.
* simplify-rtx.c (simplify_binary_operation): Likewise, avoid
performing FP operations at compile-time, if they would raise an
exception at run-time.
