try_forward_edges does not update dominance info, and merge_blocks
relies on it being up-to-date. In PR92430 stale dominance info makes
merge_blocks produce a loop in the dominator tree, which in turn makes
delete_basic_block loop forever.
Fix by freeing dominance info at the beginning of cleanup_cfg.

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.

Supporting TLS for -mpcrel turns out to be relatively simple. The
existing TLSGD and TLSLD unspecs happily can have their GOT pointer

of calls to __tls_get_addr when pc-rel won't use the GOT pointer.
Some other insns also can be reused, and just a few added.

This PR was caused by the SLP handling in get_group_load_store_type
returning VMAT_CONTIGUOUS rather than VMAT_CONTIGUOUS_REVERSE for
downward groups.
A more elaborate fix would be to try to combine the reverse permutation
into SLP_TREE_LOAD_PERMUTATION for loads, but that's really a follow-on
optimisation and not backport material. It might also not necessarily
be a win, if the target supports (say) reversing and odd/even swaps
as independent permutes but doesn't recognise the combined form.

Bump the minimum MPFR version to 3.1.0, released 2011-10-03. With this
requirement one can still build GCC with the operating system provided
MPFR on old but still supported operating systems like SLES 12 (MPFR
3.1.2) or RHEL/CentOS 7.x (MPFR 3.1.1).
This allows removing some code in the Fortran frontend, as well as
fixing PR 91828.

The 'gcc/configure' script sources all 'gcc/*/config-lang.in' files, but fails
to emit such dependency information into the build machinery. That means,
currently, when something gets changed in a 'gcc/*/config-lang.in' file, this
is not noticed, and doesn't propagate through the build machinery.

exists for Makefile fragments.
