e2177a8321 [WebAssembly] replaced .param/.result by .functype
Summary:
This makes it easier/cleaner to generate a single signature from
this directive. Also:
- Adds the symbol name, such that we don't depend on the location
  of this directive anymore.
- Actually constructs the signature in the assembler, and make the
  assembler own it.
- Refactor the use of MVT vs ValType in the streamer and assembler
  to require less conversions overall.
- Changed 700 or so tests to use it.

5e06000233 [WebAssembly] Be a little more conservative in WebAssemblyFixFunctionBitcasts
We don't have enough information to know if struct types being
bitcast will cause validation failures or not, so be conservative
and allow such cases to persist (fot now).

c7f8ab2cc1 [WebAssembly] Added default stack-only instruction mode for MC.
Summary:
Made it convert from register to stack based instructions, and removed the registers.
Fixes to related code that was expecting register based instructions.
Added the correct testing flag to all tests, depending on what the
format they were expecting so far.
Translated one test to stack format as example: reg-stackify-stack.ll

tested:
llvm-lit -v `find test -name WebAssembly`
unittests/MC/*

176975c51f [WebAssembly] Ensure bitcasts that would result in invalid wasm are removed by FixFunctionBitcasts
Rather than allowing invalid bitcasts to be lowered to wasm
call instructions that won't validate, generate wrappers that
contain unreachable thereby delaying the error until runtime.

4c8bd4af88 [WebAssembly] Convert the remaining unit tests to the new wasm-object-file target.
To facilitate this, add a new hidden command-line option to disable
the explicit-locals pass. That causes llc to emit invalid code that doesn't
have all locals converted to get_local/set_local, however it simplifies
testwriting in many cases.

f98e4f70d1 [WebAssembly] Don't abort on code with UB.
Gracefully leave code that performs function-pointer bitcasts implying
non-trivial pointer conversions alone, rather than aborting, since it's
just undefined behavior.
