  StandardInstrumentation: Fix -ir-dump-directory with -print-before-pass-number

When using -print-before-pass-number, the result would  still be
printed to stderr instead of the file. This was due to pre-filtering
cases where a temporary string for the filename prior to incrementing
the current pass number. I found the tracking of this partial filename string
confusing, so just defer that until the filename is really used.

The ugliest piece of this is IRFileDisplayName - this needs to be
computed on the original IR before before any invalidation.
