Reduce an interesting wasm to a smaller still interesting wasm. This takes an arbitrary command to run, and reduces the wasm as much as it can while keeping the behavior of that command fixed. This can be used to reduce compiler bugs in an arbitrary VM, etc.

This means you can do `rm -rf test/wasm-install` and have
it get redownloaded.

Also, fix -l and -rpath lib directories so that it can be
run out-of-tree

Begin to implement wasm threading proposal in https://github.com/WebAssembly/threads/blob/master/proposals/threads/Overview.md
This PR just has shared memory attribute with wast and binary support.

* fix type of drop, set_local, set_global, load, etc: when operand is unreachable, so is the node itself
* support binary tests properly in test/passes
* fix unreachable typing of blocks with no name and an unreachable child

* Always use scripts.test.shared for bin paths.
Update scripts/test/shared.py to add WASM_MERGE relative to build
directory. Update auto_update_tests.py to use scripts.test.shared
variables for all bin paths. Update check.py to use
scripts.test.shared for wasm-merge path (this was missing).
This allows check.py and auto_update_tests.py to be run from the
source directory using built binaries in a different location.
* --no-legalize-javascript-ffi disables JS FFI mangling.
For JS/Web platform, calls to JS imports are wrapped to convert i64 to
i32 and f32 to f64. Likewise calls from JS into exports do the inverse
wrapping. This change provides an option to disable that wrapping and
use the original types for the call.
Includes tests test/noffi_f32.asm.js and test/noffi_i64.asm.js to make
sure neither f32->f64 nor i64->i32 type mangling is happening when
--no-legalize-javascript-ffi is specified.
To fully disable JS FFI mangling when using emscripten, the fastcomp
FFI mangling must also be disabled using the
-emscripten-legalize-javascript-ffi=0 flag.

This option allows to import the linear memory from JS code instead of exporting it.
--emscripten-glue does this too but often the emscripten glue isn't needed, so this option only affects the memory.
All the code necessary for importing the memory basically already exists, so nothing except for the command line option itself had to be added.

* Refactor check.py so that groups of tests can be split into separate files
- Move helper util functions into test/shared.py
- Move scripts/support.py to test/support.py
- Split s2wasm tests into its own file
* Fix flake8 warnings for shared.py and s2wasm.py
* Move test scripts from test/ to scripts/test/

Several updates for s2wasm and its tests:
Add explicit drops where they are emitted by LLVM already
Convert loops (which are still modeled in the old way by LLVM) to wrap them in an explicit block (for the exit label). This also allows simplifying the loop creation (no need to post-process the implicit block which is the loop's body). After the engines update to 0xc we should update LLVM to model loops in the 0xc way, but for now it remains compatible with 0xb and 0xc.
Fix the order of the calls to setTee() when creating tee_locals
Add an explicit drop when creating the _start entry function wrapper if needed
Update dot_s and llvm_autogenerated tests to remove store-results optimization (and few other minor updates)
Fix the test auto-updater to fail if subprocesses fail
There still seems to be a validation failure when building libc (I think it's from the stricter drop rules, but it may be in the source rather than the compiler), but this at least makes Binaryen's tests pa
