Alex Crichton cf6d6050f7 Update test directives for wasm32-wasip1
* The WASI targets deal with the `main` symbol a bit differently than
  native so some `codegen` and `assembly` tests have been ignored.
* All `ignore-emscripten` directives have been updated to
  `ignore-wasm32` to be more clear that all wasm targets are ignored and
  it's not just Emscripten.
* Most `ignore-wasm32-bare` directives are now gone.
* Some ignore directives for wasm were switched to `needs-unwind`
  instead.
* Many `ignore-wasm32*` directives are removed as the tests work with
  WASI as opposed to `wasm32-unknown-unknown`.

//@ ignore-android since the dynamic linker sets a SIGPIPE handler (to do
// a crash report) so inheritance is moot on the entire platform
// libstd ignores SIGPIPE, and other libraries may set signal masks.
// Make sure that these behaviors don't get inherited to children
// spawned via std::process, since they're needed for traditional UNIX
// filter behavior.
// This test checks that `while echo y ; do : ; done | head` terminates
// (instead of running forever), and that it does not print an error
// message about a broken pipe.
//@ ignore-vxworks no 'sh'
//@ ignore-fuchsia no 'sh'
