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

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

Tests and drivers updated, still need to shuffle dirs.
