Sign-extension opcodes have been split into a separate proposal from
the main threads proposal, so switch them to their own target
feature. See:
https://github.com/WebAssembly/sign-extension-ops
llvm-svn: 322966
This adds code to protect WebAssembly's `trunc_s` family of opcodes
from values outside their domain. Even though such conversions have
full undefined behavior in C/C++, LLVM IR's `fptosi` and `fptoui` do
not, and only return undef.
This also implements the proposed non-trapping float-to-int conversion
feature and uses that instead when available.

Summary: WebAssemblySubtarget.cpp expects a default 'generic' CPU to exist, and this seems to be prevalent with other targets. It makes sense to have something between MVP and bleeding-edge, even though for now it's the same as MVP. This removes a warning that's currently generated.

Summary:
* Add 64-bit address space feature.
* Rename SIMD feature to SIMD128.
* Handle single-thread model with an IR pass (same way ARM does).
* Rename generic processor to MVP, to follow design's lead.
* Add bleeding-edge processors, with all features included.
* Fix a few DEBUG_TYPE to match other backends.
