3290595dd866eecab3c7044e2e3ca0adb74f1bf5 by Gennadiy Rozental <rogeeff@google.com>:

Use FlagValue<T> to represent the value of a flag. Place it directly after
FlagImpl and use a computed offset refer to it.

The offset is computed based on the assumption that the `value_` data member
is placed directly after the impl_ data member in Flag<T>.

This change will allow us to migrate to `T`-specific storage in the generic case.

This change decreases the overhead for int flags by 32 bytes.

Correct `add_subdirectory` line in CMake googletest support

Commit bcefbdcdf6ad85046ccacee0aeffba5404d3e528 added support for building with CMake against a local googletest checkout, but I missed a line when constructing the diff. Change the `add_subdirectory` line to reference the correct directories.
