Add Foreach Loop Add some data structures to represent for loops. These will be referenced during object processing to do any needed iteration and instantiation. Add foreach keyword support to the lexer. Add a mode to indicate that we're parsing a foreach loop. This allows the value parser to early-out when processing the foreach value list. Add a routine to parse foreach iteration declarations. This is separate from ParseDeclaration because the type of the named value (the iterator) doesn't match the type of the initializer value (the value list). It also needs to add two values to the foreach record: the iterator and the value list. Add parsing support for foreach. Add the code to process foreach loops and create defs based on iterator values. Allow foreach loops to be matched at the top level. When parsing an IDValue check if it is a foreach loop iterator for one of the active loops. If so, return a VarInit for it. Add Emacs keyword support for foreach. Add VIM keyword support for foreach. Add tests to check foreach operation. Add TableGen documentation for foreach. Support foreach with multiple objects. Support non-braced foreach body with one object. Do not require types for the foreach declaration. Assume the iterator type from the iteration list element type. llvm-svn: 151164

TableGen: Allow arbitrary list values as ranges of foreach The changes to FieldInit are required to make field references (Def.field) work inside a ForeachDeclaration: previously, Def.field wasn't resolved immediately when Def was already a fully resolved DefInit.
