[jit] Avoid linking the try block with the EH block as this produces spurious BBs during inlining.

The inliner could not handle optimally when we inline code inside the try block as it would be linked
with the catch block.

Since the source block would have more than one exit, the inliner would conservatively not link them together,
which hinders further local optimizations.
