[sc-dev] [commit] switch inlined

[James McCartney <asynth@xxxxxx>]

switch is now inlined when possible. In order to be inlined, the 
matching values must be literal Integers, Floats, Chars, Symbols and 
the functions must have no variables or arguments.
It uses a hash lookup internally so it should scale to any number of 
clauses.

{
	switch (x,
		\a, { 123 },
		\b, { 456 },
		\c, { 789 },
		{ 135 }
	).postln;
}.def.dumpByteCodes;
