In the WebAssembly Turbofan pipeline, inlining should come before
unrolling. When we inline a function, we link unhandled throwing calls
in it to the handler of the caller node. If a throwing call is in a
loop, we need to generate loop exits between the call and the handler if
we want to unroll later.
This CL adds dangling IfException/LoopExit nodes following each throwing
call in an inlined function. These nodes are connected as required in
inlining.
Drive-by: Remove CheckForException from tail calls, which are kNoThrow.
