Use type lookup tables in compiler
This recently regressed and stopped happening, the fix creates fake OatDexFiles so that the compiler uses the type lookup tables instead of slow FindClassDef and FindTypeId. Perf on host compile Facebook: Before: 2.49%: art::DexFile::FindClassDef(unsigned short) const 1.59%: art::DexFile::FindTypeId(char const*) const After: 0.42%: art::OatDexFile::FindClassDef(art::DexFile const&, char const*, unsigned long) 0%: art::DexFile::FindTypeId(char const*) const 0%: art::DexFile::FindClassDef(unsigned short) const Average install (N6P 960 mhz average of 40 samples): 38.2s -> 35.64s Bug: 32641252 Test: test-art-host, adb install.
