Make rustc test suite pass

[bjorn3]

cc #247

I got a branch to test it at https://github.com/bjorn3/rustc_codegen_cranelift/tree/wip_test_rustc_testsuite.

Excluding the following tests: src/test/run-pass/{asm-*,abi-*,extern/,panic-runtime/,panics/,unsized-locals/,proc-macro/,threads-sendsync/,thinlto/,simd/}

The following run-pass tests fail:

test result: FAILED. 1401 passed; 577 failed; 805 ignored; 0 measured; 0 filtered out

Note: those 805 ignored are tests passed when I ran it previous time.

The most common runtime errors are:

• thread 'main' panicked at 'assertion failed: `(left == right)`
    left: `22`,
   right: `0`', sysroot_src/src/libstd/sys/unix/mutex.rs:112:9
  

• thread 'main' panicked at 'assertion failed: c.borrow().is_none()', sysroot_src/src/libstd/sys_common/thread_info.rs:37:26
  

[bjorn3]

Ignoring all emscripten ignored tests brings failed down to 525. Emscripten doesn't support threading, u/i128 and inline asm just like cg_clif.

[bjorn3]

Filled #388 for multithreading support.

And down to 510 thanks to 2ce5387.

1f00b7b fixed several tests.

[bjorn3]

Down from 312 to 169 in 22331ad. This works around #412.

[bjorn3]

I reduced the ifmt.rs test to:

macro_rules! t {
    ($a:expr, $b:expr) => { assert_eq!($a, $b) }
}

pub fn main() {
    t!(format!("{:.*}", 4, "aaaaaaaaaaaaaaaaaa"), "aaaa"); // with -Zopt-level=2
// thread 'main' panicked at 'assertion failed: `(left == right)`
//   left: `"aaaaaaaaaaaaaaaaaa"`,
//  right: `"aaaa"`', rust/src/test/run-pass/ifmt.rs:6:5
    t!(format!("{:.3e}", 1.2345e6f64), "1.234e6"); // with -Zopt-level=1
// thread 'main' panicked at 'assertion failed: noborrow', sysroot_src/src/libcore/num/bignum.rs:481:1
}

[bjorn3]

mir_overflow_off.rs want assert_eq!(u8::shl(1, 9), 2_u8);

[bjorn3]

Most of the runtime panics are from unaligned slices, which is understandable as #348 is not yet fixed. I didn' investigate the cause of struct-return.rs, union-c-interop.rs and a few others panicking.

The "invalid ebb reference" errors will be fixed in rust-lang/rust#58902.
