Message:

Make it possible to enable LLVM FastISel
​https://bugs.webkit.org/show_bug.cgi?id=143489

Reviewed by Michael Saboff.

The decision to enable FastISel is made by Options.h|cpp, but the LLVM library can disable it if it finds that it is built
against a version of LLVM that doesn't support it. Thereafter, JSC::enableLLVMFastISel is the flag that tells the system
if we should enable it.
