The deafult quasi

`hello ${ 42 }`

generates 

var $__0 = Object.freeze({ cooked: Object.freeze(["hello "]) }); 
traceur.runtime.defaultQuasi($__0, 42); 

We can simplify this a lot for the default quasi and just generate:

"hello " + (42) + ""

Once we have one string we can skip empty strings. For example

`${1}${2}${3}`

could naïvely be generated as

"" + (1) + "" + (2) + "" + (3) + ""

but once we have on string we can skip future empty string... resulting in

"" + (1) + (2) + (3)

we can also optimize away the parentheses
