[Ada] Refine generation of range checks to happen in front end

base type of the result to ensure that proper overflow and range
checks are generated.  If the target is a fixed-point tyoe,

rather than relying on Apply_Type_Conversion_Checks, which might
simply set the Do_Range_Check flag and rely on the backend to
add the check.

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

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.

* include/Makefile.am: Add new <bits/unique_lock.h> header.
* include/Makefile.in: Regenerate.
* include/bits/std_mutex.h [!_GLIBCXX_USE_C99_STDINT_TR1] (mutex)

Fix ceil_log2(0) (PR 86644)

This PR shows a pathological case in which we try SLP vectorisation on
dead code.  We record that 0 bits of the result are enough to satisfy
all users (which is true), and that led to precision being 0 in:

static unsigned int
vect_element_precision (unsigned int precision)
{
  precision = 1 << ceil_log2 (precision);
  return MAX (precision, BITS_PER_UNIT);
}

ceil_log2 (0) returned 64 rather than 0, leading to 1 << 64, which is UB.
