[Bug translator/11473] New: Support optional "as VALUE" in foreach loops

["jistone at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

The current foreach syntax is:

  foreach (VAR in ARRAY [ limit EXP ]) STMT
  foreach ([VAR1, VAR2, ...] in ARRAY [ limit EXP ]) STMT

I propose making it:

  foreach (VAR in ARRAY [ as VALUE ] [ limit EXP ]) STMT
  foreach ([VAR1, VAR2, ...] in ARRAY [ as VALUE ] [ limit EXP ]) STMT

This way we can avoid repeated array lookups for the common case that you're
only interested in ARRAY[VAR1,VAR2,...] anyway.
