Stage 1 test failure on master branch

[Phlosioneer]

I'm getting a test failure for ui-fulldeps/proc-macro/load-panic.rs on my local machine:

    Auto merge of #49141 - gnzlbg:simd_select, r=alexcrichton

    adds simd_select intrinsic

    The select SIMD intrinsic is used to select elements from two SIMD vectors using a mask:
unix_sub@DevWindows ~/r/rust>

I'm running on the linux subsystem for windows, which is:

unix_sub@DevWindows ~/r/rust> uname -a
Linux DevWindows 4.4.0-43-Microsoft #1-Microsoft Wed Dec 31 14:42:53 PST 2014 x86_64 x86_64 x86_64 GNU/Linux

I have never had any issues compiling before. (DevWindows is my computer's name)

I'm running the tests using the command:

unix_sub@DevWindows ~/r/rust> ./x.py test --stage 1

[hanna-kruppe]

This is a proc macro test so it's expected that it doesn't work on stage1 right now. #49219 should fix that.

[oli-obk]

It should still be marked //ignore-stage1

[Phlosioneer]

I'm guessing run-pass-fulldeps/compiler-calls.rs and run-pass-fulldeps/proc-macro/span-api-tests.rs should be ignored too. I've added them to a PR.

I'm now getting an error for double_bind() in src/libstd/net/tcp.rs:1199. It's panicking because a double-bind is allowed?

There's no associated error message, it's just a raw panic!().

Again, same test command; just a vanilla stage-1 test.

[Phlosioneer]

double_bind() is also failing with stage 2 (./x.py test). I'm going to make a new issue for it.

[jonas-schievink]

This is fixed.
