[Bug 488354] Re: NS_InvokeByIndex in xptcinvoke_arm.cpp is not Thumb-2 safe for Lucid

Got a build and tested it against lucid firefox-3.5.

I didn't appear to get any problems (I'm reporting this bug using the Thumb-2 xulrunner library).
Attached is a gdb session transcript, where I set a breakpoint on the NS_InvokeByIndex implementation: the code is definitely Thumb-2, as can be observed by the instruction offsets not divisible by 4, and the mixture of instruction sizes (among other things).

I step some calls and returns through NS_InvokeByIndex; it seems to be
doing the right thing.
