Most places can use PrintFatalError as the unwinding mechanism was not
used for anything other than printing the error. The single exception
was CodeGenDAGPatterns.cpp, where intermediate errors during type
resolution were ignored to simplify incremental platform development.
This use is replaced by an error flag in TreePattern and bailout earlier
in various places if it is set.

In order to avoid rev-lock with Clang when moving to the new API, also
preserve the current API temporarily and insert a shim to implement the
new API in terms of the old.

This patch adds a preprocessor that can expand nested for-loops for
saving some copy-n-paste in *.td files.
The preprocessor is not yet integrated with TGParser, and so it has
no direct effect on *.td inputs. However, you may preprocess an td
input (and only preprocess it).
To test the proprecessor, type:
tblgen -E -o $@ $<
