Add convenient overloads for CreateInsertElement and CreateExtractElement methods in IRBuilder

Browse Source 
Summary:
This pathc add convenient overloads for CreateInsertElement and CreateExtractElement methods in IRBuilder
where vector index can be uint64_t instead of Value*.

Test Plan: Unit test included.
