Ioanna Dimitriou 1872e216d0 Bug 1695778 - (Core-Wasm-EH-Ion) part 1: try-catch/throw without reftypes. r=rhunt 
Adds basic support for the WebAssembly Exception Handling proposal.
In particular this implements the instructions `try-catch/catch_all` and `throw`
for exceptions carrying values of non reference type.

Spec for try-catch:
https://github.com/WebAssembly/exception-handling/blob/master/proposals/exception-handling/Exceptions.md#try-catch-blocks

Spec for throw:
https://github.com/WebAssembly/exception-handling/blob/master/proposals/exception-handling/Exceptions.md#throwing-an-exception

Comments:

- Adds [SMDOC] documentation for WebAssembly Exception Handling in Ion.
- Does not add support for WebAssembly values of type reftype inside exceptions.
- Does not implement the instructions `rethrow` or `try-delegate`.
- Due to the above, the tests that contain `rethrow`, `try-delegate`, or involve
  exceptions carrying reftype values, are made conditional on the test being run
  with the baseline compiler.
- There are tests added:
  + Tests ensuring that side effects in try blocks are tracked correctly in the
    handlers (side-effects.js).
  + Tests with complex control flow, and with exceptions being thrown by direct
    and by indirect function calls (calls.js).
  + The single memory test in instructions.js is moved to memory.js, where it is
    generalised.
  + Some very basic tests related to Simd128 values (Wasm vectype) are added in
    validation.js, instructions.js, side-effects-in-try.js, and calls.js.
