llvm/utils/TableGen/TableGen.cpp
Eric Christopher d568b3f552 Revert r134921, 134917, 134908 and 134907. They're causing failures 
in multiple buildbots.

// TableGen is a tool which can be used to build up a description of something,
// then invoke one or more "tablegen backends" to emit information about the
// description in some predefined format. In practice, this is used by the LLVM
// code generators to automate generation of a code generator through a
// high-level description of the target.
