tgsi: track max array per file

NOTE IN[] and OUT[] don't need (have?) ArrayID's.. and TEMP[] can
optionally have them.  So we implicitly assume that ArrayID==0 always
exists for each file.  This is why array_max[file] is never less than
zero.

You can tell from indirect_files(_read/written) if the legacy array-
id zero was actually used.
