Changes in directory llvm/lib/AsmParser:
Lexer.l updated: 1.82 -> 1.83
ParserInternals.h updated: 1.46 -> 1.47
llvmAsmParser.y updated: 1.275 -> 1.276
---
Log message:
For PR950: http://llvm.org/PR950 :
Retain the signedness of the old integer types in a new TypeInfo structure
so that it can be used in the grammar to implement auto-upgrade of things
that depended on signedness of types. This doesn't implement any new
functionality in the AsmParser, its just plumbing for future changes.
