83115e9eb8 libgomp/test: Add flags to find libatomic in build-tree testing
Add flags to find libatomic in build-tree testing, fixing a catastrophic
libgomp testsuite failure with `riscv*-*-linux*' targets, which imply
`-latomic' with the `-pthread' GCC option, implied in turn by the
`-fopenacc' and `-fopenmp' options, removing failures like:

.../bin/riscv64-linux-gnu-ld: cannot find -latomic
collect2: error: ld returned 1 exit status
compiler exited with status 1
FAIL: libgomp.c/../libgomp.c-c++-common/atomic-18.c (test for excess errors)
Excess errors:
.../bin/riscv64-linux-gnu-ld: cannot find -latomic

UNRESOLVED: libgomp.c/../libgomp.c-c++-common/atomic-18.c compilation failed to produce executable

and bringing overall test results for the `riscv64-linux-gnu' target
(here with the `x86_64-linux-gnu' host and RISC-V QEMU in the Linux user
emulation mode as the target board) from:

		=== libgomp Summary ===

# of expected passes		90
# of unexpected failures	3267

62aee289e4 Add OpenACC 2.6 `serial' construct support
The `serial' construct (cf. section 2.5.3 of the OpenACC 2.6 standard)
    is equivalent to a `parallel' construct with clauses `num_gangs(1)
    num_workers(1) vector_length(1)' implied.
    These clauses are therefore not supported with the `serial'
    construct. All the remaining clauses accepted with `parallel' are also
    accepted with `serial'.

    The `serial' construct is implemented like `parallel', except for
    hardcoding dimensions rather than taking them from the relevant
    clauses, in `expand_omp_target'.

    Separate codes are used to denote the `serial' construct throughout the
    middle end, even though the mapping of `serial' to an equivalent
    `parallel' construct could have been done in the individual language
    frontends. In particular, this allows to distinguish between compute
    constructs in warnings, error messages, dumps etc.

5d183d1740 Warn about inconsistent OpenACC nested reduction clauses
OpenACC (cf. OpenACC 2.7, section 2.9.11. "reduction clause";
	this was first clarified by OpenACC 2.6) requires that, if a
	variable is used in reduction clauses on two nested loops, then
	there must be reduction clauses for that variable on all loops
	that are nested in between the two loops and all these reduction
	clauses must use the same operator.
	This commit introduces a check for that property which reports
	warnings if it is violated.
