* Part of bug 122:Reid Spencer2004-05-264-133/+101
| | | | | | | | | | | This change removes the BuildBytecodeInfo flag from the SlotCalculator class. This flag was needed to distinguish between the Bytecode/Writer and the AsmWriter. Now that AsmWriter doesn't use SlotCalculator, we can remove this flag and simplify some code. Also, some minor name changes to CachedWriter.h needed to be committed (missed in previous commit). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13785 91177308-0d34-0410-b5e6-96231b3b80d8
