8980281184 fix llvm assert on version string with git sha
LLVM's CodeViewDebug pass misparses the version string when it contains
a git revision so stop doing that.  This only affected Windows builds.

2e5115b068 Add run compiler command
'zig run file.zig' builds a file and stores the artifacts in the global
cache. On successful compilation the binary is executed.

'zig run file.zig -- a b c' does the same, but passes the arguments a,
b and c as runtime arguments to the program. Everything after an '--' are
treated as runtime arguments.

On a posix system, a shebang can be used to run a zig file directly. An
example shebang would be '#!/usr/bin/zig run'. You may not be able pass
extra compile arguments currently as part of the shebang. Linux for example
treats all arguments after the first as a single argument which will result
in an 'invalid command'.

Currently there is no customisability for the cache path as a compile
argument. For a posix system you can use `TMPDIR=. zig run file.zig` to
override, in this case using the current directory for the run cache.

The input file is always recompiled, even if it has changed. This is
intended to be cached but further discussion/thought needs to go into
this.

Closes #466.

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.

3d1732ef6c Fix OpqaueType usage in exported c functions

manually after generation.

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.

60b2031831 improvements to stack traces
* @panic generates an error return trace
 * printing an error return trace no longer interferes with
   normal stack traces.
 * instead of ignore_frame_count, we look at the return address
   when you call panic, and that's the first stack trace function
   makes stack traces much cleaner - the error return trace
   flows gracefully into the stack trace
