[RFC 13/14] Load macros before uses

This hoists the various calls to 'load' to an earlier spot in
read.scm.  Without this patch, the call to logit
/cmd-define-rtl-version would not be expanded, leading to a mysterious
error about trying to 'apply' a syntax transformer.  That is, this is
another situation where the old code assumed that macro expansion
could be interleaved with evaluation.
