Subject: Add Value Accessors
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=96a9f78c4aa1bc188f3f7ee869bed44cb7a6ff0e;p=oota-llvm.git

Add Value Accessors

Add accessors to get Record values by Init name.  This lets us look up
Record values whose names are not yet fully resolved.  More work
toward paste.
