Fix bugs in V128 support based on results from testing against simd spec test.
...
These is one test failure remaining with V128 global variables.
* Fix trunc_sat. We need both the largest float that can be converted to an int
and the largest int, they are not the same number.
* Implement calling of functions that take V128 by passing in two i64's.
* Improve support for V128 in spectests. Parse binary modules with the same
features as the outer spectest. Fix compilation error involving Result in
emitted .rs file. Handle V128 in more cases when producing .rs file. Parse
the wast script with SIMD enabled.
* Adjust the WAVM spectest so that it parses with WABT and mostly passes with
wasmer. Wabt is particular about ints not having decimal places and floats
having decimal places. Wasmer does not support mutable globals or shared
memory. Tests of shuffles are disabled. Some assert_invalid tests that wabt
won't even parse are disabled.

Try a new list of optimization passes.
...
A few notes:
a) the inliner doesn't help because all the calls are indirect and not even opt -O2 can figure out which functions they're actually calling.
b) aggressive instruction combining is not a super-set of the instruction combiner. Instcombine is made up of a large number (probably 10,000s) of patterns, and some particularly slow ones were taken out and moved to the aggressive instruction combiner. Aggressive instcombine *only* runs that handful of optimizations, which fired zero times on our example wasm files.
c) NewGVN is not ready for production, it has asserts that fire when building sqlite or cowsay. This is why sqlite didn't build with the llvm backend.
d) Scalar-replacement-of-aggregates (sroa) is a strict superset of promote-memory-to-registers (mem2reg), and you probably want sroa because it's usually faster. It also fires 10,000s more times than mem2reg on lua.wasm.
e) Aggressive-dead-code-elimination was only deleting as much regular dead-code-elimination, but is slower because it depends on a postdominator tree (PDT) analysis that. Other passes don't need PDT so we'll have to build it for just this one pass (as opposed to regular dominator-tree which is reused by many passes). I've replaced this with bit-tracking dead-code-elimination which deletes more code than dce/adce.

Add a signal handler for macos and linux.
...
Implementation Notes:
- To avoid setjmp, longjmp, and the mess that those create, we instead set the interrupting
context of the signal handler to return into the `throw_trap` routine. To my surprise,
this actually works. The stack ends up getting unwound normally and the memory-oob error
is caught by the trampoline.
