[CIR] Force cir.cmp to always return bool (llvm#1110)
It was always the intention for `cir.cmp` operations to return bool result. Due to missing constraints, a bug in codegen has slipped in which created `cir.cmp` operations with result type that matches the original AST expression type. In C, as opposed to C++, boolean expression types are "int". This resulted with extra operations being codegened around boolean expressions and their usage. This commit both enforces `cir.cmp` in the op definition and fixes the mentioned bug.
