Subject: Remove the last use of getUnsignedVersion and getSignedVersion from VMCore.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d54d8fa45a1f189580934259fcac3fc3c663810e;p=oota-llvm.git

Remove the last use of getUnsignedVersion and getSignedVersion from VMCore.
ConstantInt doesn't care about the sign of the type it represents. It only
cares about the bitwidth so there is no need to make the sign of the type
match the SExt or ZExt constant expression.
