Arnaud A. de Grandmaison 2be921adc4 InstCombine: Improve the result bitvect type when folding (cmp pred (load (gep GV, i)) C) to a bit test. 
The original code used i32, and i64 if legal. This introduced unneeded
casts when they aren't legal, or when the index variable i has another
type. In order of preference: try to use i's type; use the smallest
fitting legal type (using an added DataLayout method); default to i32.
A testcase checks that this works when the index gep operand is i16.
