runtime: flag static variables as no-pointers
Variables in data sections of 32-bit executables interfere with
garbage collector's ability to free objects and/or unnecessarily
slow down the garbage collector.
This changeset moves some static variables to .noptr sections.
'files' in symtab.c is now allocated dynamically.
