Because in `std::tr1::tuple_element` the first template parameter should be of type int (https://gcc.gnu.org/onlinedocs/libstdc++/libstdc++-html-USERS-4.4/a00547.html), but the code inserts a size_t, the first template parameter should be casted to int before, to get rid of the following errors:
googletest-src/googletest/include/gtest/gtest-printers.h:957:60: error: conversion from ‘long unsigned int’ to ‘int’ may change value [-Werror=conversion]
struct tuple_element : ::std::tr1::tuple_element<I, Tuple> {};
and
googletest-src/googletest/include/gtest/gtest-printers.h:961:56: error: conversion from ‘long unsigned int’ to ‘int’ may change value [-Werror=conversion]
const typename ::std::tr1::tuple_element<I, Tuple>::type>::type get(
GTEST_TEST_FILTER_ENV_VAR_ was used to specify an environment variable to obtain
the default test filter from. By default it was unset which broke
"--test_filter" for bazel. This CL eliminates GTEST_TEST_FILTER_ENV_VAR_ and
explicitly obtains the default test filter from the environment variable
TESTBRIDGE_TEST_ONLY if it exists.
This canonicalizes demangled names by omitting a nested inline namespace within namespace std if the name of the nested namespace begins with a double underscore. This improves compatibility with libc++.
This allows doing things like TEST_P(TestFixture, MAYBE(TestName))
for nicer conditional test disabling.

Tested:
Added unit tests MacroNamingTest and MacroNamingTestNonParametrized.
