Matthias Hausner 1a6d1eca32 Implement @patch annotation for patch class members 
Allow members of patch classes to be annotated with @patch. The VM
ignores the annotation. I simply replaces the original method
if the name matches, or reports an error if field names match.

Adding a bit is_patched to members to do more checking remains a
TODO. There are currently no unused bits available, and I don’t want
to increase the size of Function objects for this.

Matthias Hausner e11ca24053 Use metadata annotation @patch for patch classes 
Annotate patch classes and top-level patch functions with @patch
instead of the pseudo-keyword patch. This allows the analyzer
to read patch files, and matches the syntax that dart2js uses.

The deprecated syntax is still supported, but a warning is printed when detected.

Stephen Adams 2bb2a12720 Avoid multiple reallocations of StringBuffer._parts 
The original code

    _parts = [ str ];

allocated a _GrowableList backed by a single element _List.
Subsequent calls to _parts.add() grows the backing list to 2, then 4, etc.

On a dart2js workload, allocating with a reasonable initial capacity
reduces the number of _List objects allocated by 8%, with 4% reduction in
_List bytes allocated.

sra@google.com 6467b4302d dart2js implementation of StringBuffer.writeAll that optimizes better. 
Sometimes we can avoid the StringBuffer object:

    t1 = new P.StringBuffer(leftDelimiter);
    t1.writeAll$2(parts, ", ");
    t1 = t1._contents += rightDelimiter;
    return t1.charCodeAt(0) == 0 ? t1 : t1;
-->
    t1 = P.StringBuffer__writeAll(leftDelimiter, parts, ", ") + rightDelimiter;
    return t1.charCodeAt(0) == 0 ? t1 : t1;

Also updated tests with missing cases.

StringBuffer.writeAll is expected by pub tests to not be patched or inlined.  I'll fix that and redo.
