PATCH: Handle symbols in messages

[Jim Blandy <jimb at redhat dot com>]

I've committed the following.  There are many more places where concat
is needed, but cgen now runs with '-v -v -v -v'; we can fix others as
we find them.

2005-01-20  Jim Blandy  <jimb@redhat.com>

	* utils.scm (concat): New function.
	* insn.scm (-sub-insn-make!): Use concat instead of string-map.
	* rtl.scm (rtx-dump): Same.
	* semantics.scm (semantic-compile): Same.
