Adding support for __builtin_annotation with an intrinsic called llvm.annotation. This is similar to llvm.var.annotation but is applied to expressions.

+<h5>Syntax:</h5>
+<pre>
+ declare i32 @llvm.annotation(i32 <val>, i8* <str>, i8* <str>, i32 <int> )
+</pre>
+
+<h5>Overview:</h5>
+<p>This is an overloaded intrinsic. You can use '<tt>llvm.annotation</tt>' on
+any integer bit width. Not all targets support all bit widths however.
+</p>
+
+<h5>Arguments:</h5>
+
+<p>
+The first argument is an integer value (result of some expression),
+the second is a pointer to a global string, the third is a pointer to a global
+string which is the source file name, and the last argument is the line number.
+</p>
+
+<h5>Semantics:</h5>
+
+<p>
+This intrinsic allows annotations to be put on arbitrary expressions
+with arbitrary strings. This can be useful for special purpose optimizations
+that want to look for these annotations. These have no other defined use, they
+are ignored by code generation and optimization.
