Switch -ftrack-macro-expansion=2 on by default.
This switches the compiler to -ftrack-macro-expansion=2 by default.
Tested and bootstrapped on x86_64-unknown-linux-gnu against trunk.
libcpp/
* init.c (cpp_create_reader): Switch -ftrack-macro-expansion=2 on
by default. Add comments.
gcc/docs/
* cppopts.texi: Adjust for enabling -ftrack-macro-expansion=2 by
default.
