 Changes to the WebAssembly Backend
 ----------------------------------
 
-The default target CPU, "generic", now enables the `-mnontrapping-fptoint`
-and `-mbulk-memory` flags, which correspond to the [Bulk Memory Operations]
-and [Non-trapping float-to-int Conversions] language features, which are
-[widely implemented in engines].

-A new Lime1 target CPU is added, -mcpu=lime1. This CPU follows the definition of
-the Lime1 CPU [here], and enables -mmultivalue, -mmutable-globals,
--mcall-indirect-overlong, -msign-ext, -mbulk-memory-opt, -mnontrapping-fptoint,
-and -mextended-const.
