Jakob Kummerow 0661a0dd8f [stringrefs] Fix inlining, and some corner case bugs 
1) Inlining functions that contain stringref operations require builtin
   calls to be marked as kNoThrow appropriately (or have exception
   handling support in the graph).
2) Some overly-large inputs for string creation hit DCHECKs before
   getting to the places where they would have thrown an orderly
   exception.
3) We still had a known issue that some exceptions thrown by JS-focused
   code were erroneously catchable by Wasm.
4) When string.concat attempted to create a too-long string, it ran into
   a DCHECK because we didn't clear the "thread in wasm" flag.
5) The builtin call for string.concat was erroneously marked as
   kEliminatable, which could cause the trap get eliminated.
