Simon Pilgrim af689eb896 [APInt] Add APInt::setBits() method to set all bits in range ... The current pattern for setting bits in range is typically: Mask |= APInt::getBitsSet(MaskSizeInBits, LoPos, HiPos); Which can be particularly slow for large APInts (MaskSizeInBits > 64) as they require the allocation memory for the temporary variable. This is one of the key compile time issues identified in PR32037. This patch adds the APInt::setBits() helper method which avoids the temporary memory allocation completely, this first implementation uses setBit() internally instead but already significantly reduces the regression in PR32037 (~10% drop). Additional optimization may be possible. I investigated whether there is need for APInt::clearBits() and APInt::flipBits() equivalents but haven't seen these patterns to be particularly common, but reusing the code would be trivial.
