Subject: Use the version of getValue that takes the type plane instead of the type
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=35d2ca672bb400ee69dbbe0fef362e4e9a57e5e4;p=oota-llvm.git

Use the version of getValue that takes the type plane instead of the type
if possible.  This provides a consistent 8.5% speedup.
