	* app/appenv.h
	* app/main.c: removed "use_mmx" and the MMX detection.

	* app/base/Makefile.am: build the MMX detection unconditionally
	as it's already #ifdef'ed in the source.

	* app/base/detect-mmx.h: added a header for detect-mmx.S

	* app/base/base-config.[ch]: added the "use_mmx" boolean.

	* app/base/base.c: call intel_cpu_features() here.

	* app/paint-funcs/paint-funcs.c: #include "base/base-config.h".

	* app/floating_sel.c
	* app/core/gimpimage.c: removed commented out cruft.

	* app/core/gimplayer.c: gimp_layer_new_from_tiles(): pass the
	gimage instead of NULL to gimp_layer_new() because layers have to
	be created in an image context now
	(checked gimp_layer_new_from_tile()'s callers if this is
	semantically correct).
