Fix the use of linemap_add and remove unnecessary kludge
libcpp/
* line-map.c (linemap_add): Assert that reason must not be
LC_RENAME when called for the first time on a "main input file".
c-family/
* c-pch.c (c_common_read_pch): Call linemap_add with LC_ENTER as it's
the first time it's being called on this main TU.
gcc/lto/
* lto-lang.c (lto_init): Likewise. Also, avoid calling
linemap_add twice.
gcc/fortran/
* scanner.c (load_file): Don't abuse LC_RENAME reason while
(indirectly) calling linemap_add.
