Feature request: specify mangled name for output

[lauriro]

Although silly request, someone may desire to specify a mangled variable name, like in Dean Edwards original packer output eval(function(p,a,c,k,e,r){.

Comment annotation seems to be the best place for that:

(function(one /*#mangleTo:H*/, two /*#mangleTo:i*/) { /*..*/ })(1, 2);
// results (function(H,i){ /*..*/ )(1,2);
