* Added a new file: beintlive_t.h which subsumes all interferene/liveness checks
- it uses the new liveness checking algos in ana/irlivechk.h - value_dominates, etc. was erased from bera.h because it does not belong there * bechordal.c features an experimental coloring (by defualt disabled by macro) which can color the routine in a single pass without building the "borders". A long term goal is to disable borders completely but they are used in other places, too. * The 1st parameter of values_interfere is now a birg and not a be_lv_t. There is now a special routine lv_values_interfere() for those who want to use the computed liveness explicitly. changing the parameter makes it more easy to switch to other liveness implementations. All other files were modified to respect the changes [r13762]
