Use ATTRIBUTE((used)) for symbols used only in inline asm.

This may fix compilation for optimized builds with GCC or clang where
the compiler would otherwise decide that those symbols are unused.

Inreased debugging level for catching oob accesses to 'main' arrays.

If enabled, this makes the following arrays be allocated statically:
spriteext, spritesmooth, sector, wall, sprite, tsprite, while
necessarily disabling the clipshape feature (because it relies on
setting sector/wall to different malloc'd block temporarily).

To compile, pass DEBUGANYWAY=1 in addition to RELEASE=0 to 'make',
and it's really only useful with CC=clang, of course.
