[patch, fortran, committed] Fix PR31972, ICE on Hollerith in TRANSFER.

[Brooks Moses]

This is a trivial two-line fix.  Once we know the size of a BT_HOLLERITH 
expression, we already know how to export it to the memory buffer, since 
all BT_HOLLERITH expressions have representation.string defined.

This patch also adds a check to make sure that we aren't transferring a 
value _to_ a Hollerith, because that makes no sense.

Regression tested on powerpc-apple-darwin8.9.0, committed to trunk.
