When a symbol cannot be demangled in ada_demangle a new demangled VEC
will be allocated without deleting the demangled VEC already in use.

It started failing after the following commit: 32e90dc6a0cda45 ("PR
rtl-optimization/61047").
The change that made xtensa backend go ICE looks completely unrelated,
and indeed, the issue is caused by the side effect of
compute_frame_size() function call hidden in the
INITIAL_ELIMINATION_OFFSET macro. This call updates the value of the
xtensa_current_frame_size static variable, used in "return" instruction
predicate. Prior to the change the value of xtensa_current_frame_size was
set to 0 after the end of epilogue generation, which enabled the "return"
instruction for the CALL0 ABI, but after the change the additional
INITIAL_ELIMINATION_OFFSET calls make xtensa_current_frame_size non-zero
and "return" pattern unavailable.
Get rid of the global xtensa_current_frame_size and
xtensa_callee_save_size variables by moving them into the
machine_function structure. Implement predicate for the "return" pattern
as a function. Don't communicate completion of epilogue generation
through zeroing of xtensa_current_frame_size, add explicit epilogue_done
variable to the machine_function structure. Don't update stack frame
layout after the completion of reload.

When using cgo -gccgo calls to C.GoString, C.GoStringN, and C.GoBytes
are turned into calls to __go_byte_array_to_string and
__go_string_to_byte_array. Those functions were removed when the string
code was copied from Go 1.7, but we still need them for cgo. While cgo
should be updated, old versions will exist for some time.

Use mvifdiff and stamp files to track whether a .gox file has changed.
When package A depends on package B, and we rebuild package B, only
rebuild package A if package B's .gox file changes. This is safe
because when package A imports package B it only reads package B's .gox
file. This means that changes that do not affect export information
will not cause dependent packages to be recompiled.

This patch from Le-Chun Wu adds two new shadow warning flags for
C and C++:
-Wshadow=local which warns if a local variable shadows another local
variable or parameter,
-Wshadow=compatible-local which warns if a local variable shadows
another local variable or parameter whose type is compatible with
that of the shadowing variable.
It is already on the google/main branch (Google ref 39127) and was
previously submitted by Diego Novillo and reviewed on
http://codereview.appspot.com/4452058
I addressed the review comments and made the following changes:
- Add -Wshadow=global (the default alias for -Wshadow).
- Make the documented options -Wshadow=global, -Wshadow=local
and -Wshadow=compatible-local (with hidden undocumented aliases
-Wshadow-local and -Wshadow-compatible-local for compatibility).
- The -Wshadow=global, -Wshadow=local and -Wshadow=compatible-local
relationships are expressed in common.opt instead of in opts.c
and documented in invoke.texi.
- The "previous declaration" warnings were turned into notes and use
the (now) existing infrastructure instead of duplicating the warnings.
The testcases have been adjusted to expect the notes.
- The conditional change in name-lookup.c for non-locals (where we
don't want to change the warnings, but just check the global ones)
has been dropped.
- Use warning_at in c-decl.c (warn_if_shadowing).

* tree-vect-slp.c (vect_get_and_check_slp_defs): New parameter SWAP.
Check slp defs for COND_EXPR by swapping/inverting operands if the
new parameter SWAP indicates so.
(vect_build_slp_tree_1): New parameter SWAP. Check COND_EXPR stmt
is isomorphic to the first stmt via swapping/inverting. Store swap
information in the new parameter SWAP.
(vect_build_slp_tree): New local array SWAP and pass it to function
vect_build_slp_tree_1. Cleanup result handling code for function
call to vect_get_and_check_slp_defs. Skip operand swapping if the
order of operands has been fixed as indicated by SWAP[i].
