Include the filename being looked up in an error message. This gives us stuff
...
like this:
t3.c:5:10: error: 'vers2.h' file not found
#include xstr(INCFILE(2).h)
^
instead of:
t3.c:5:10: error: file not found
#include xstr(INCFILE(2).h)
^
which is useful if the #include name is generated through macro expansion.

Refactor the paths used for checking and getting the spelling of #include
...
filenames (and also '#pragma GCC dependency' of course). Now, assuming
no cleaning is needed, we can go all the way from lexing the filename to
doing filename lookups with no mallocs. This speeds up user PP time from
0.077 to 0.075s for Cocoa.h (2.6%).
