[PATCH] D35040: [IR] Implement Constant::isNegativeZeroValue/isZeroValue/isAllOnesValue/isOneValue/isMinSignedValue for ConstantDataVector without going through getElementAsConstant

[Craig Topper via Phabricator via llvm-commits]

craig.topper created this revision.

Currently these methods call ConstantDataVector::getSplatValue which uses getElementsAsConstant to create a Constant object representing the element value. This method incurs a map lookup to see if we already have created such a Constant before and if not allocates a new Constant object.

This patch changes these methods to use getElementAsAPFloat and getElementAsInteger so we can just examine the data values directly.
