This non-publishable new crate contains a test suite for the
`wasmer-runtime-core` crate. So far, the test suite is rather small,
but it aims to be extended in a close future.
856: Add WASI support to C API r=MarkMcCaskey a=MarkMcCaskey
This is an additive change (with one unrelated clean up of `*mut ptr -> *const ptr`). It exposes the functions to get a WASI import object. It also implements a function on import object to get an `import` with namespace and name.
These changes should be okay to ship now, we can follow up to finish adding methods to ImportObject on the C API side and start migrating away from `*imports`.

901: Set target triple and datalayout when creating the LLVM module. r=nlewycky a=nlewycky
We were giving LLVM a triple and datalayout only when producing native code from the LLVM IR. With this change, we tell LLVM as early as possible so that the entire optimization stack knows that it's safe to use target-specific constructs (including target intrinsics `@llvm.x86.sse2.ucomieq.sd`) as well as cost models (for autovectorization) and knowing the bitwidth of the registers so that we can know it's profitable to eliminate redundant extend/truncate casts.

904: Use getelementptr instruction instead of int_to_ptr and ptr_to_int. r=nlewycky a=nlewycky
The main part of this change is that we no longer turn pointers into integers to do arithmetic on them, then turn them back into pointers. Doing so is a signal to LLVM that it should not attempt to analyze the provenance of the pointers, disabling some optimizations. Using getelementptr allows us to perform arithmetic on pointers while keeping them in pointer types, which LLVM can then analyze.
Most of the textual change is a refactoring to reorder the operations. Previously the bounds checking and determining of the base and bounds were combined because you could put both into the same match, since both actions are performed differently depending on whether the memory is static or dynamic. In this case, we simply check the type twice and do two different things, with comments labelling the steps.

ptr_to_int and int_to_ptr are not treated the same as type-safe pointer operations. LLVM intentionally performs fewer optimizations to code using the former as compared with the latter. We don't need that in our code, standard pointer optimizations are safe for us.
877: Reimplement F32Min, F32Max, F64Min and F64Max. r=nlewycky a=nlewycky
# Description
Reimplement F32Min, F32Max, F64Min and F64Max.
Adds XMM8--15 registers. Adds VMOVA, VBLEND and VXORP, and the VCMPUNORD and VCMPORD comparisons.
Fixes 419 test failures.

887: Get aggressive about running cargo check over all packages with all features. r=nlewycky a=nlewycky
Fixes the one issue uncovered. The capstone disassembling support in the LLVM backend was broken. Fixed by removing it. Instead, use the `--llvm-object-file` flag to get a finished object file to disassemble with any disassembler.

889: fix(singlepass-backend) Use wasmparser from `runtime-core` r=Hywan a=Hywan
The `wasmer-runtime-core` crate re-exports the `wasmparser`
crate. This patch updates the `singlepass-backend` crate to use
`wasmparser` through the `wasmer-runtime-core` crate, which removes a
direct dependency for this crate.

885: fix(cranelift-backend) Remove broken (and useless?) debug code r=nlewycky a=Hywan
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.
The `debug` feature is kept in `Cargo.toml` to activate `wasmer-runtime-core/debug`.

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.
