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.
