Improve C11 atomics support:

- Generate atomicrmw operations in most of the cases when it's sensible to do
  so.
- Don't crash in several common cases (and hopefully don't crash in more of
  them).
- Add some better tests.

We now generate significantly better code for things like:
_Atomic(int) x;
...
x++;

On MIPS, this now generates a 4-instruction ll/sc loop, where previously it
generated about 30 instructions in two nested loops.  On x86-64, we generate a
single lock incl, instead of a lock cmpxchgl loop (one instruction instead of
ten).

Beef up the testing of our 'ld' invocation on linux to cover static
linking. About to fix a bug here and there was no good test case.

Check for warnings in a bunch of the linker invocations, and add one
with both -static-libgcc and -static on the commandline.

Fix a warning in the latter case due to a backwards short circuiting ||
operator in the driver. No real functionality changed here, just allows
the driver to properly consume -static-libgcc when -static is also
specified.

Fix the emission of the copy-initialization of a block capture
from a lambda capture when the capture is not trivially-copyable.

Centralize and refine the __unknown_anytype argument rules
and be sure to apply them whether or not the debugger gave
us a method declaration.
