Martijn Dekker 2758e5db19 Update #pragmas to make clang be quiet about historic practice 
This adds a #pragma to disable -Wdeprecated-register* on newer
versions of clang. We could remove all use of the register keyword
instead, as modern compilers ignore it. But it's not harmful, and
for the time being I prefer not to do doing any reformatting or
changing the historic character of this code base.

The #pragmas are removed from src/lib/libast/include/ast.h, because
they're better placed in src/lib/libast/features/common which
generates ast_common.h which is included by everything.
