Chris Lattner ec39f095f5 Fix a major source of compile-time slowness at -O0 -g by optimizing ... the storage of !dbg metadata kinds in the instruction themselves. The on-the-side hash table works great for metadata that not-all instructions get, or for metadata that only exists when optimizing. But when compile-time is everything, it isn't great. I'm not super thrilled with the fact that this plops a TrackingVH in Instruction, because it grows it by 3 words. I'm investigating alternatives, but this should be a step in the right direction in any case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99957 91177308-0d34-0410-b5e6-96231b3b80d8		2010-03-30 23:03:27 +00:00
