Feature request: Change all type names from AX to TArgX

I work with legacy code bases which have hardcoded constants for A0, A1, etc (unavoidable). To use gtest, I replace all template arguments A0, A1, ... A10 with TArg0, TArg1, etc.

This is no fault of Google test, but I was wondering if it would be possible for you to make this change in the gtest code base. I believe it would help others working with legacy code bases with hardcoded constants too, especially with common names like A1, etc. I'm happy to make this change myself and open a PR, with the gtest team's approval.

As a side note, I also have to do this kind of search-replace on the protobuf source code, where I replace NAME with GNAME and MAX_TYPE with GMAX_TYPE.

Thanks!

Start by locating the gtest template arguments named A0 through A10 and identify every affected part of the gtest codebase. Review the existing tests before changing names; done means the requested arguments consistently use TArg0 through TArg10 and the test suite still passes.
