	PR fortran/47592
	* trans-stmt.c (gfc_trans_allocate): For deferred character
	length allocations with SOURCE, store to the values and string
	length to avoid calculating twice.  Replace gfc_start_block
	with gfc_init_block to avoid unnecessary contexts and to keep
	declarations of temporaries where they should be. Tidy up the
	code a bit.
