mesa/st/st_glsl_to_tgsi_temprename.cpp: Fix compilation with MSVC

If <windows.h> is included then max is a macro that clashes
with std::numeric_limits::max, hence undefine it.
For some reason the struct access_record is not recognizes
outside the anonymouse namespace, make it a class.
The patch successfully was tested on AppVeyor.
