Rework expr_landor

Browse Source 
so that it also is called from the precedence parser.  This
is complicated by the fact that something needs to be done before
the second operand is parsed in a single pass compiler, so it
doesn't quite fit into expr_infix itself.  It turns out the smallest
code changes result when expr_landor remains separate.  But it can
be tidied a bit.
