2019-11-12Add OpenACC 2.6 `serial' construct supportMaciej W. Rozycki11-13/+146
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. 2019-11-12 Maciej W.

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.
