lang/gcc8-devel: Remove

With the release of GCC 8.5 the GCC 8 release series has reached
end of life.

This also means the end of weekly snapshots. Remove lang/gcc8-devel
which has been tracking those and redirect to lang/gcc8 and that
final release instead.

lang/gcc8-devel: Update to the 20210512 snapshot of GCC 8.4.1

This brings two back ports for the aarch64 back end, three for the
low-level RTL optimizers, and one for the tree optimizers, plus one
for the C front end.

This probably will be the final snapshot of the GCC 8 release branch.

lang/gcc8-devel: Update to the 20210505 snapshot of GCC 8.4.1

optimizers/middle end (3), debug information, RTL optimizers (4),
the C++ front end and libstdc++ (2).

lang/gcc8-devel: Update to the 20210429 snapshot of GCC 8.4.1

This will be one of the last snapshots before the GCC 8 branch closes.

It brings 16 back ports for the tree optimizers, middle end, and
link-time optimization (LTO), six around debug information, another
six for the lower level optimizers, two for the aarch64 back end,
one each for x86 and powerpc (nee rs6000), five for the C front end,
14 for C++ and another two for libstdc++.

lang/gcc8-devel: Update to the 20210422 snapshot of GCC 8.4.1

Update to the 20210325 snapshot of GCC 8.4.1.

Update to the 20210318 snapshot of GCC 8.4.1.

This brings one backport for the aarch64 back end and eight for the
tree optimizers/middle end.

Update to MPC version 1.2.0 with the following changes:
 - New functions:
   . mpc_sum
   . mpc_dot
 - Several functions are more robust with a reduced exponent range
   (for example corresponding to IEEE 754 binary formats).
 - New mpcheck tool for comparison with the native C library (which
   is not installed by default).

Bump all directly dependent ports. Do not bump those indirectly
dependent via the lang/gcc* family since their run-time dependencies
and code generated should not be affected.

  Until that changes (or GCC changes) we need to avoid using vec_step as a
  variable name.
