Currently __builtin_annotation() only annotates an i32.

i32 __builtin_annotation(i32, string);

Applying it to i64 (e.g., long long) generates the following IR.

        trunc i64 {{.*}} to i32
        call i32 @llvm.annotation.i32
        zext i32 {{.*}} to i64

The redundant truncation and extension make the result difficult to use.

This patch makes __builtin_annotation() generic.

        type __builtin_annotation(type, string);

For the i64 example, it simplifies the generated IR to:

        call i64 @llvm.annotation.i64

Bring llvm.annotation* intrinsics support back to where it was in llvm-gcc: can

annotate global, local variables, struct fields, or arbitrary statements (using
the __builtin_annotation), rdar://8037476.
