[PATCH] [mep] delete unused constraint-related macros and functions
- From: Nathan Froyd <froydnj at mozilla dot com>

- Subject: [PATCH] [mep] delete unused constraint-related macros and functions
mep uses {constraints,predicates}.md and #if 0'd out the old macro versions.
In the interest of not keeping dead code around, I'd like to delete these.
I think this falls under the obvious rule, so I'll commit this in a couple of
days after waiting to hear from DJ.
Tested by building mep-elf.
