a282ee62d3 Bug 660039: Provide a WeakMap usable from C++. r=jorendorff 
Remove WeakMap class; implement the JavaScript object using functions static to jsweakmap.cpp.

Define a new WeakMap class template, parameterized by Key and Value types,
and accepting a MarkPolicy argument saying how to mark them.

Add assertions to check that we check and set the right mark bits, and
tests that trip them in the presence of mistakes in earlier revisions of
this patch.

6a958619a0 Automatically turn debug mode on/off when adding/removing debuggees. 
This allows most of the tests to run without the -d command-line flag.

Now a compartment is in debug mode if
 * JSD1 wants debug mode on, thanks to a JS_SetDebugMode* call; OR
 * JSD2 wants debug mode on, because a live Debug object has a debuggee
   global in that compartment.

Since this patch only adds the second half of the rule, JSD1 should be
unaffected.

The new rule has three issues:

1. When removeDebuggee is called, it can cause debug mode to be turned
   off for a compartment. If any scripts from that compartment are on
   the stack, and the methodjit is enabled, returning to those stack
   frames will crash.

2. When a Debug object is GC'd, it can cause debug mode to be turned off
   for one or more compartments. This causes the same problem with
   returning to deleted methodjit code, but the fix is different: such
   Debug objects simply should not be GC'd.

3. Setting .enabled to false still does not turn off debug mode
   anywhere, so it does not reduce overhead as much as it should.

A possible fix for issue #1 would be to make such removeDebuggee calls
throw.  The fix to issues #2 and #3 is to tweak the rule--and to tweak
the rule for Debug object GC-reachability.
