b01c50d6fa find libc and zig std lib at runtime 
this removes the following configure options:
 * ZIG_LIBC_LIB_DIR
 * ZIG_LIBC_STATIC_LIB_DIR
 * ZIG_LIBC_INCLUDE_DIR
 * ZIG_DYNAMIC_LINKER
 * ZIG_EACH_LIB_RPATH
 * zig's reliance on CMAKE_INSTALL_PREFIX

these options are still available as command line options, however,
the default will attempt to execute the system's C compiler to
collect system defaults for these values.

aa2995ee39 fix invalid codegen for error return traces across suspend points 
See #821

Now the code works correctly, but error return traces are missing
the frames from coroutines.

84e952c230 fix await multithreaded data race 
coro return was reading from a value that coro await was
writing to. that wasn't how it was designed to work, it
was an implementation mistake.

this commit also has some work-in-progress code for fixing
error return traces across suspend points.

556f22a751 different way of fixing previous commit 
get_fn_type doesn't need the complete parameter type, it
can just ensure zero bits known.

90598b4631 fix assert on self-referencing function ptr field 
The construct `struct S { f: fn(S) void }` is not legal because structs
are not copyable but it should not result in an ICE.

Fixes #795.
