Erik Eckstein 1a01f870e1 AllocStackHoisting: fix a quadratic complexity bug when merging stack locations. 
Use consecutive instruction numbers to check for overlapping instead of iterating over the instruction list.

This fixes a compile time problem which shows up if there are many stack locations in a large basic block.
