fix Issue 13089 - Spurious 'is not nothrow' error on static array initialization

Bypass attribute check on direct invariant calls.
fix Issue 13030 - DMD assertion fails at mtype.c:697 if delegate has an argument name
fix Issue 13117 - Executable size of hello world explodes from 472K to 2.7M

- This problem seems to stem from mixed writeable flags for the
  .deh/.minfo sections in PIC/non-PIC code. The ld.bfd linker would
  still try to bracket the sections, even though it previously mapped
  them to different segments, thereby creating one huge segment which
  contains all read-only and all writeable data plus the big hole in
  between them.

- fixed by always marking those sections as writeable
regression tests for binary size

- test will fail when binaries increase by about 10%
  above the current size
