Karthik Bhat 5ab7795649 Allow vectorization of intrinsics such as powi,cttz and ctlz in Loop and SLP Vectorizer. 
This patch adds support to vectorize intrinsics such as powi, cttz and ctlz in Vectorizer. These intrinsics are different from other
intrinsics as second argument to these function must be same in order to vectorize them and it should be represented as a scalar.

TailCallElim Improve 'tail' call marking in TRE. A bootstrap of clang goes from 375k calls marked tail in the IR to 470k, however this improvement does not carry into an improvement of the call/jmp ratio on x86. The most common pattern is a tail call + br to a block with nothing but a 'ret'. 2014-05-05 23:59:03 +00:00
