c5a69cee9f Add x86 legalization for fcvt_to_uint_sat.i32x4 
This converts an `f32x4` into an `i32x4` (unsigned) with rounding by using a long sequence of SSE4.1 compatible instructions.

b1c7c1401e Fix incorrect scaling for SaveXmm128Far. 
The `SaveXmm128Far` unwind op should have a 32-bit unscaled value.

The value was accidentally scaled down by 16 while calculating whether or not
the `SaveXmm128` or `SaveXmm128Far` unwind op should be used.

3a33749404 Remove 'set frame pointer' unwind code from Windows x64 unwind. 
This commit removes the "set frame pointer" unwind code and frame
pointer information from Windows x64 unwind information.

In Windows x64 unwind information, a "frame pointer" is actually the
*base address* of the static part of the local frame and would be at some
negative offset to RSP upon establishing the frame pointer.

Currently Cranelift uses a "traditional" notion of a frame pointer, one
that is the highest address in the local frame (i.e. pointing at the
previous frame pointer on the stack).

Windows x64 unwind doesn't describe such frame pointers and only needs
one described if the frame contains a dynamic stack allocation.

Fixes #1967.

a7c6433773 wasmtime: Support reference types in the Rust API 
This is a mix of exposing new things (e.g. a `Table::fill` method) and extending
existing support to `externref`s (e.g. `Table::new`).

2ce2dd0203 wasmtime: add build-time option for parallel compilation (#1903) 
When running in embedded environments, threads creation is sometimes
undesirable. This adds a feature to toggle wasmtime's internal thread
creation for parallel compilation.

60681d7019 Add __dso_handle to exception list of deprecated export symbols 
When compiling C to WASM with clang-8, __dso_handle is a global
that maybe exported but that currently is not whitelisted along
with __heap_base and _data_end to be handled as allowable depricated
exports. This PR adds the case for __dso_handle.

bffd54c016 wasmtime: Implement global.{get,set} for externref globals (#1969) 
* wasmtime: Implement `global.{get,set}` for externref globals

We use libcalls to implement these -- unlike `table.{get,set}`, for which we
create inline JIT fast paths -- because no known toolchain actually uses
externref globals.
