Rename loc_t to lincol_t

SVN Trunk revision 180430 fails to compile on AIX 5.3 TL4, with this error:

/mnts/cdstools/build/source/gcc-r180430/gcc/tree-diagnostic.c:59: error:
conflicting types for =E2=80=98loc_t=E2=80=99

Grepping around the system headers, I find a typedef struct localeinfo_tabl=
e to
loc_t in /usr/include/sys/localedef31.h.  I've verified this is present in =
AIX
5.3 TL4, 6.1 and 7.3.

As the use of 'loc_t' is isolated to tree-diagnostic.c, I simply renamed it=
 to
'lincol_t' so I could get on with things.  I've attached the diff, but some=
one
is far more than welcome to come up with a better name that doesn't conflict
with AIX.  (Or someone could make it so AIX never appears in my life again,
that would work too.)
