[cilkplus] Fix precompiled header bug (PR cilkplus/70865)

The file cilk.h defines the memory managed cilk_trees variable, but
fails to include the header in the GTFILES list. When a precompiled
header is loaded, the array is then not properly restored and points
to garbage memory, causing a segfault. This patch fixes the problem by
adding the cilk files to GTFILES and gengtype.c.

Bootstrapped and regression tested on x86_64-linux.

2016-05-16  Ryan Burn  <contact@rnburn.com>

  * Makefile.in (GTFILES): Add cilk.h and cilk-common.c.
  * gengtype.c (open_base_files): Add cilk.h to ifiles.
