[WebAssembly] Remove uses of ThreadModel Summary: In the clang UI, replaces -mthread-model posix with -matomics as the source of truth on threading. In the backend, replaces -thread-model=posix with the atomics target feature, which is now collected on the WebAssemblyTargetMachine along with all other used features. These collected features will also be used to emit the target features section in the future. The default configuration for the backend is thread-model=posix and no atomics, which was previously an invalid configuration. This change makes the default valid because the thread model is ignored. A side effect of this change is that objects are never emitted with passive segments. It will instead be up to the linker to decide whether sections should be active or passive based on whether atomics are used in the final link.

WebAssembly: add vtable test The test will mainly be useful to check that the .s file assembles and relocates properly because vtables reference functions in their data section. llvm-svn: 256102

; Test that simple vtables assemble as expected.

; The class hierarchy is:
; struct A;
; struct B : public A;
; struct C : public A;
; struct D : public B;
; Each with a virtual dtor and method foo.
[WebAssembly] Add -m:e to the target triple. This enables ELF-style name mangling, which primarily means using ".L" for private symbols. llvm-svn: 257020
