This PR does the following.
Removes dependency on WTF-iOS, JavaScriptCore-iOS and ToolExecutable-iOS xcconfig files

Modifies the `message` and `stack` properties on the ErrorInstance object to be enumerable so they can be grabbed on the Titanium side.

Disabled the LLINT_C_LOOP execution model and enables JIT(DFG_JIT, FTL_JIT and YARR_JIT are still disabled)

There is also a new build script that builds WTF and JavaScriptCore on a per architecture basis so the logs the output to a text file so build errors are easy to tack down.
