Convert x.toString() to ""+x instead of x+""
 2012-11-12 00:47:56 -08:00

b49230ab8d convert x.toString() to ""+x instead of x+"" 
In some places this can save one byte in whitespace, e.g. after return.
Example:

function f(arg) {
        // return""+arg - no space between return and ""
        return arg.toString();
}

1a5fd3e052 optimization for if/break as first statement in a loop body 
for(...; x; ...) if (y) break; → for(...; x&&!y; ...);

similarly for `while` and some combinations (i.e. the `break` appears in the
`else` clause, etc.)

5276a4a873 add AST_Accessor and AST_SymbolAccessor node types 
AST_Accessor will represent the function for a setter or getter.  Since they
are not mangleable, and they should not introduce a name in scope, we have a
new node for their name (AST_SymbolAccessor) which doesn't inherit from
AST_SymbolDeclaration.

774f2ded94 minor optimization 
for `==` or `!=` against a constant, prefer to display the constant first.
should help a bit after gzip, i.e.:

    typeof foo=="undefined"
    ^^^^^^    ^^^^^^^^^^^^^

vs:

    "undefined"==typeof foo
    ^^^^^^^^^^^^^^^^^^^     (longer sequence that could repeat)

idea stolen from closure.
