064452423a Don't include custom chkstk on MSVC

f9f6bd0589 Tweak definition of probestack functions 
It looks like the old `__rust_probestack` routine is incompatible with newer
linux kernels. My best guess for this is that the kernel's auto-growth logic is
failing to trigger, causing what looks like a legitimate segfault to get
delivered. My best guess for why *that's* happening is that the faulting address
is below `%rsp`, whereas previously all faulting stack addresses were above
`%rsp`. The probestack routine does not modify `%rsp` as it's probing the stack,
and presumably newer kernels are interpreting this as a legitimate violation.

This commit tweaks the probestack routine to instead update `%rsp` incrementally
as probing happens. The ABI of the function, however, requires that `%rsp`
isn't changed as part of the function so it's restored at the end to the
previous value.

681aaa914d Use the Rust implementation of udivsi3 on ARM 
Although compiler-rt presumably has a more optimized implementation written in
assembly, it appears buggy for whatever reason, causing #173.

For now let's see if integration into rust-lang/rust will work with the
Rust-defined implementation!

2f2bb32e40 Use traits instead of macros for shift intrinsics 
This is an attempt to tidy up the definition of intrinsics by making them more
rust-like at the definition site and using traits instead of macros for the
definition. Additionally the helper macro, `intrinsics!`, now fills in a
definition for #[cfg]'d off intrinsics when compiling with C code

644a1c9ac9 fix infinite recursion in divmoddi4 / mulodi4 
on ARMv7-M processors, divmoddi4 was calling mulodi4 and mulodi4 was calling

wrapping multiplication in divmoddi4.

57085be2ea ARM: keep some non-aeabi symbols around 
- multi3: there's no aeabi equivalent
- divmod{s,d}i4: these are directly called by __aeabi_{l,i}divmod
- add{s,d}f3: required by the C sub{s,d}f3 implementation

but make sure they also use the AAPCS calling convention

Jorge Aparicio
dfa7b161aa use AAPCS calling convention on all aeabi intrinsics 
also, on ARM, inline(always) the actual implementation of the intrinsics so we
end with code like this:

```
00000000 <__aeabi_dadd>:
    (implementation here)
```

instead of "trampolines" like this:

```
00000000 <__aeabi_dadd>:
    (shuffle registers)
    (call __adddf3)

00000000 <__adddf3>:
    (implementation here)
```

37d349015e Disable quickcheck tests on mips 
Two reasons:
    * the C versions __divti3 and __modti3 are apparently broken,
      at least when used in quickcheck. They change their own arguments.
    * compiler_rt's support for mips is disabled already on clang [1].
      Its desireable to support working "cargo test" on that compiler
      as well, and not greet the tester with linker errors.
