Detailed Description
This structure is used to efficiently record the current status of live SSA_NAMES when building a conflict graph. LIVE_BASE_VAR has a bit set for each base variable which has at least one ssa version live. LIVE_BASE_PARTITIONS is an array of bitmaps using the basevar table as an index, and is used to track what partitions of each base variable are live. This makes it easy to add conflicts between just live partitions with the same base variable. The values in LIVE_BASE_PARTITIONS are only valid if the base variable is marked as being live. This delays clearing of these bitmaps until they are actually needed again.
