f101775380 fix(cranelift-backend) Remove broken (and useless?) debug code. 
This debug code is broken (it doesn't compile). It can be assumed
nobody uses it, and can be considered as dead code. As such, this PR
removes it.

2c5c1b1c2c For floating point operations, allow inputs to be arbitrary, including SNaNs. 
Instead of ensuring outputs are arithmetic NaNs on every function, we tag them as pending such a check, so that a sequence of computation can have a single canonicalization step at the end.

There's an extra wriggle for SIMD. The Wasm type system only indicates them as V128, so it's possible that we might do computations as F32x4Add, I8x16Add, F64x2Add in a row with no other computations in between. Thus, most SIMD functions apply pending canonicalizations to their inputs, even integer SIMD operations.

81be25d970 feat(runtime-core) Add documentation and make macros more readable. 
After a long time, the macros are easy to read, but not at first
glance. I hope this PR will improve the situation: Same syntax used
everywhere, more spaces…

Merge #863 
863: Rewrite Min/Max to handle all cases correctly. Fixes 545 spectest failures. r=nlewycky a=nlewycky

# Description
The llvm backend was not quite following the Wasm spec for {F32,F64,F32x4xF64x2}{Min,Max}. We used the `@llvm.minnum` and `@llvm.maxnum` intrinsics which don't handle the corner cases the same. When we tried to use `@llvm.minimum` and `@llvm.maximum` which do, we get an internal error from the x86 backend. I was hoping that crash would go away with the upgrade to LLVM 9, but it does not.

Reimplement these operations using plain LLVM instructions.

# Review

- [x] Add a short description of the the change to the CHANGELOG.md file
