Dan Gohman a6ecd1a73f Add "volatile" and "memory" clobber to asm! that doesn't fall through.
Use the "volatile" option and the "memory" clobber on inline asm that does
things like return directly, to reduce the chances of compilers rearranging
the code.

Alex Crichton 45cd956acc Prepare this crate for more wasm32 compatibility
This commit prepares the build script for a wasm32 target that doesn't use
Emcripten, notably forcing the `mem` feature to get activated and forcibly
ignoring the `c` feature, even if activated, for the wasm32 target.

drop binfmt_misc dependency

Instead use the Cargo runner feature. The binfmt_misc approach requires running a privileged
container for setup. Not all docker setups support privileged containers so the test suite should be
more accessible with this change as no privileged container is needed.

bors 5b96befbc5 Auto merge of #115 - Amanieu:linux-arm-atomic, r=alexcrichton
Add atomic support for pre-ARMv6 on Linux

This uses the [kernel user helpers](https://www.kernel.org/doc/Documentation/arm/kernel_user_helpers.txt) which are available starting from kernel 2.6.15. Since Rust currently requires 2.6.18 at a minimum, this should be fine in practice. I did not include support for 64-bit atomics since that functionality is only available in kernel 3.1.

This PR allows Rust to work on older ARM versions such as ARMv4 and ARMv5 with the full libstd.

Implement x86 chkstk in "rust"

cc #183

Basically the same as the x86_64 ones, except `__alloca` doesn't need to fix the parameter register. I've manually verified that the disassembly is the same, and that these work in a compiled rust program.

The second commit disables compiling probestack functions for `feature = mangled-names`. They aren't needed during testing because they aren't comparison tested and the unmangled versions are the ones that actually get used.

Update rustbuild commentary

r? @nikomatsakis

This is the reason that https://github.com/rust-lang/rust/pull/44509 doesn't work - the `rustbuild` feature _is_ actually used, it was just incorrectly documented here and I missed it.

Update the gcc crate to 0.3.53 and disable compilation warnings

The update is needed because you'd otherwise get a deprecation warning about `Config` being deprecated, as rust-lang/rust has updated the gcc crate.

The compilation warnings are inside the compiler-rt submodule, about which we don't have
direct control over, so we disable them.
