combine: Allow combining two insns to two insns

This patch allows combine to combine two insns into two.  This helps
in many cases, by reducing instruction path length, and also allowing
further combinations to happen.  PR85160 is a typical example of code
that it can improve.

This patch does not allow such combinations if either of the original
instructions was a simple move instruction.  In those cases combining
the two instructions increases register pressure without improving the
code.  With this move test register pressure does no longer increase
noticably as far as I can tell.

(At first I also didn't allow either of the resulting insns to be a
move instruction.  But that is actually a very good thing to have, as
should have been obvious).

lra: consider clobbers when selecting hard_regno to spill

The idea behind the rclass loop in spill_hard_reg_in_range() seems to
be: find a hard_regno, which in general conflicts with reload regno,
but does not do so between `from` and `to`, and then do the live range
splitting based on this information. To check the absence of conflicts,
we make use of insn_bitmap, which does not contain insns which clobber
the hard_regno.

[libgomp, nvptx] Handle per-function max-threads-per-block in default dims

Currently parallel-loop-1.c fails at -O0 on a Quadro M1200, because one of the
kernel launch configurations exceeds the resources available in the device, due

libsanitizer: Mark REAL(swapcontext) with indirect_return attribute on x86

Cherry-pick compiler-rt revision 337603:

When shadow stack from Intel CET is enabled, the first instruction of all
indirect branch targets must be a special instruction, ENDBR.

lib/asan/asan_interceptors.cc has

...
  int res = REAL(swapcontext)(oucp, ucp);
...

REAL(swapcontext) is a function pointer to swapcontext in libc.  Since
swapcontext may return via indirect branch on x86 when shadow stack is
enabled, as in this case,

int res = REAL(swapcontext)(oucp, ucp);
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^  This function may be
returned via an indirect branch.

Here compiler must insert ENDBR after call, like

call *bar(%rip)
endbr64

I opened an LLVM bug:

https://bugs.llvm.org/show_bug.cgi?id=38207

to add the indirect_return attribute so that it can be used to inform
compiler to insert ENDBR after REAL(swapcontext) call.  We mark
REAL(swapcontext) with the indirect_return attribute if it is available.

This fixed:

[libgomp, openacc, testsuite] Fix async/wait logic in lib-13.f90

The purpose of the lib-13.f90 test-case is to test acc_wait_all_async.  The
test indeed calls acc_wait_all_async, but then subsequentlys calls
acc_wait_all, so the acc_wait_all_async functionality is not tested.
Furthermore, all acc_async_test calls are placed in a location where they are
not guaranteed to succeed, which explains why there's an xfail for the lower
optimization levels.

This patch fixes the problems by replacing acc_wait_all with an acc_wait on
the async id used for the acc_wait_all_async call, and moving the
acc_async_test calls to the correct locations.

Move std::unique_lock definition to a separate header

This will allow std::mutex and std::lock_guard to be used elsewhere in
the library without pulling in the whole of <chrono>.

Previously the whole of <bits/std_mutex.h> was conditional on the
_GLIBCXX_USE_C99_STDINT_TR1 macro, but only the std::unique_lock members
that use <chrono> facilities should depend on that. std::mutex only
needs to depend on _GLIBCXX_HAS_GTHREADS and std::lock_guard can be
defined unconditionally.

Some parts of <bits/std_mutex.h> and <mutex> are based on code in
<ext/concurrence.h> which dates from 2003. However, the std::unique_lock
implementation was added in 2008 by r135007, without using any earlier
code. Therefore the new header file has copyright years 2008-2018.

Add initial version of C++17 <memory_resource> header

polymorphic_allocator ended up looking almost the same anyway.

Fix segfault in -fsave-optimization-record (PR tree-optimization/86636)

There are various ways that it's possible for a gimple statement to
have an UNKNOWN_LOCATION, and for that UNKNOWN_LOCATION to be wrapped
in an ad-hoc location to capture inlining information.

For such a location, LOCATION_FILE (loc) is NULL.

Various places in -fsave-optimization-record were checking for
  loc != UNKNOWN_LOCATION
and were passing LOCATION_FILE (loc) to code that assumed a non-NULL
filename, thus leading to segfaults for the above cases.

This patch updates the tests to use
  LOCATION_LOCUS (loc) != UNKNOWN_LOCATION
instead, to look through ad-hoc location wrappers, fixing the segfaults.

rs6000: Improve vsx_init_v4si

This changes vsx_init_v4si to be an expander.  That way, no special
cases are needed anymore for special arguments: the normal RTL passes
can deal with it.

* config/rs6000/rs6000-p8swap.c (rtx_is_swappable_p): Adjust.
* config/rs6000/rs6000-protos.h (rs6000_split_v4si_init): Delete.
* config/rs6000/rs6000.c (rs6000_expand_vector_init): Always force
the elements into a register.
(rs6000_split_v4si_init_di_reg): Delete.
(rs6000_split_v4si_init): Delete.
* config/rs6000/vsx.md (unspec): Delete UNSPEC_VSX_VEC_INIT.
(vsx_init_v4si): Rewrite as a define_expand.

rs6000: Generate rl*imi for memory some more

An rl<wd>imi instruction is often written like "(a << 8) | (b & 255)".
If "b" now is a byte in memory, combine will combine the load with the
masking (with 255 in the example), since that is a single instruction;
and then the rl*imi isn't combined from the remaining pieces.

This patch adds a splitter to make combine handle this case.

* config/rs6000/rs6000.md (splitters for rldimi and rlwimi with the
zero_extend argument from memory): New.
