By adding fallback definitions of std::intmax_t and std::uintmax_t it's
possible to define <ratio> without _GLIBCXX_USE_C99_STDINT_TR1. This in
turn allows most of <chrono> to be defined, which removes the dependency
on _GLIBCXX_USE_C99_STDINT_TR1 for all of the C++11 concurrency features.

Currently, when a kernel is lauched with too many workers, it results in a cuda
launch failure.  This is triggered f.i. for parallel-loop-1.c at -O0 on a Quadro
M1200.

This patch detects this situation, and errors out with a hint on how to fix it.

Build and reg-tested on x86_64 with nvptx accelerator.

The current code in reg_nonzero_bits_for_combine allows using the
reg_stat info when last_set_mode is a different integer mode.  This is
completely wrong for non-pseudos.  For example, as in the PR, a value
in a DImode hard register is set by eight writes to its constituent
QImode parts.  The value written to the DImode is not the same as that
written to the lowest-numbered QImode!

In testcase lib-12.f90, 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 problem by moving the acc_async_test calls to the correct
locations.

	to correct locations.  Remove xfail.

From-SVN: r262990

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.

Reg-tested on x86_64 with nvptx accelerator.

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.

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.
