Exporting a publicly visible class with a generic name like
"variable_entry" via ir_variable_refcount.h is kind of mean.
Many IR transformers would like to define their own "variable_entry"
class. If they accidentally include this header, the compiler/linker
may get confused and try to instantiate the wrong variable_entry class,
leading to bizarre runtime crashes.
The hope is that renaming this one will allow .cpp files to safely
declare and use their own file-scope "variable_entry" classes.
This avoids crashes caused by converting src/glsl to automake.

Standard library functions in C++ are in the std namespace. When using
C++-style header files for the standard library, some compilers, such as
Sun Studio, provide symbols only for the std namespace and not for the
global namespace.
This patch adds using statements for standard library functions. Another
option could have been to prepend standard library function calls with
'std::'.
This patch fixes several compilation errors with Sun Studio.
