Shortcuts for wasm

wah	wasm
(0 = 1)	(set_local 0 (i32.const 1))
(%$a + %$b)	(f64.add (get_local $a) (get_local $b))
(0 + 1)	(i32.add (i32.const 0) (i32.const 1))
(0.0 + 1.0)	(f64.add (f64.const 0) (f64.const 1))

• Adds infix operators: *, +, -, /, ==, >, <, >=, <=
• Supports (0 = 1) shortcut for set_local
• Supports bare numbers that become f64.const if they have a decimal point, and i32.const if they don't.
• Supports type inference by walking up the tree, paying attention to param and local types.
