Restore line_table and input_location before calling fatal_error when failing a
pch load

With this patch, the fatal_error is properly reported:

> $BUILDDIR/stage1-gcc/xg++ -B $BUILDDIR/stage1-gcc -Werror -Winvalid-pch -Wno-deprecated -c conftest.cc
conftest.cc:1:0: fatal error: had to relocate PCH
 #include "conftest.h"
