Dan Gohman 284384b640 [WebAssembly] Support inline asm constraints of type i16 and similar.

Dan Gohman a774d719a0 [WebAssembly] Fix inline asm support for i64 operands.

Dan Gohman 53828fd777 [WebAssembly] Emit .param, .result, and .local through MC. 
This eliminates one of the main remaining uses of EmitRawText.

Dan Gohman 3d4a20662a [WebAssembly] Make bogus inline asm strings in tests be comments. 
These tests aren't testing that the result is valid syntax; they're testing
that the compiler emits the inline asm operands correctly.

Dan Gohman 4ba4816b97 [WebAssembly] Enable register coloring and register stackifying. 
This also takes the push/pop syntax another step forward, introducing stack
slot numbers to make it easier to see how expressions are connected. For
example, the value pushed in $push7 is popped in $pop7.

And, this begins an experiment with making get_local and set_local implicit
when an operation directly uses or defines a register. This greatly reduces
clutter. If this experiment succeeds, it may make sense to do this for
const instructions as well.

And, this introduces more special code for ARGUMENTS; hopefully this code
will soon be obviated by proper support for live-in virtual registers.
