+- Revised handling of annotation statements.  Now they come in two forms:
+    1. __builtin_annot("format", x1, ..., xN)
+       (arbitrarily many arguments; no code generated, even if some
+        of the xi's were spilled; no return value)
+    2. __builtin_annot_intval("format", x1)
+       (one integer argument, reloaded in a register if needed,
+        returned as result).
+
+- Related clean-ups in the handling of external functions and 
+  compiler built-ins.
