From-SVN: r232549
This patch adds a pass that collects information that is common to
all uses of an SSA name X and back-propagates that information up
the statements that generate X. The general idea is to use the
information to simplify instructions (rather than a pure DCE) so
I've simply called it gimple-ssa-backprop.c, to go with
tree-ssa-forwprop.c.
At the moment the only use of the pass is to remove unnecessary
sign operations, so that it's effectively a global version of
fold_strip_sign_ops. I'm hoping it could be extended in future
to record which bits of an integer are significant. There are
probably other potential uses too.
A later patch gets rid of fold_strip_sign_ops.
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.

Commit the vtable verification feature. This feature is designed to
detect, at run time, if/when the vtable pointer in a C++ object has
been corrupted, before allowing virtual calls through that pointer.
If pointer corruption is detected, execution of the program is halted.

The intent of the phases was to have a high-level but mutually exclusive
accounting of compile time. We want to track compile time in a way that
tells us which conceptual phases are taking the most time. That intent
is not currently satisfied. This patch restores that intent.
Add code to verify that the sum of the phase times is less than the total
time, to detect when phases are overlapped. A slight amount of leeway is
required due to time jitters. This verification is done as the last step
in printing timevars so that any timevar information is not lost.
Rename the phases to be clearer about what they measure, so that they
are less likely to be modified to be overlapping. The primary example
is to change TV_PHASE_GENERATE to TV_PHASE_LATE_ASM, meaning late work
on the assembly. This name change avoids confusion n moving the timevar
start call after the call to lang_hooks.decls.final_write_globals, which
prevents overlapping phases.
Each implementation of lang_hooks.decls.final_write_globals, is responsible
for starting and stopping its own phases. Each implementation currently has
a first phase of TV_PHASE_DEFERRED for front-end work deferred until after
parsing is complete. The second phase has been renamed from TV_PHASE_CGRAPH
to TV_PHASE_OPT_GEN, to better reflect its use as the main optimization
and generation phase. This phase accounts for 70%-80% of compilation time
during bootstrap. The third phase is TV_PHASE_DBGINFO, except in cp/decl2.c,
where it is TV_PHASE_CHECK_DBGINFO because cc1plus mixes checking in with
debug info generation. In langhooks.c, write_global_declarations was
using TV_PHASE_CHECK_DBGINFO, but it was doing no checking. So, it now
uses TV_PHASE_DBGINFO.
The changes to LTO are significant. First, initialization now uses
TV_PHASE_SETUP. Reading files now uses TV_PHASE_STREAM_IN. Writing files
now uses TV_PHASE_STREAM_OUT. The remaining phase is TV_PHASE_OPT_GEN
(formerly TV_PHASE_CGRAPH). Finally, because LTO is treated as a front
end, TV_PHASE_PARSING and TV_PARSE_GLOBAL active around it. It is not
parsing, and so those timers should not be active. Rather than make all
front ends manage them, we turn them off as the first thing in LTO and turn
them back on as the last thing.
Tested on x86_64.

Turn TV_PHASE_PARSING off then back on again, because LTO is pretending
to be a front end, but is not one.
