IR: Swap order of name and value in MDEnum

Browse Source 
Put the name before the value in assembly for `MDEnum`.  While working
on the testcase upgrade script for the new hierarchy, I noticed that it
"looks nicer" to have the name first, since it lines the names up in the
(somewhat typical) case that they have a common prefix.
