f1f998e071 improve cmpxchg
* remove @cmpxchg, add @cmpxchgWeak and @cmpxchgStrong
   - See explanations in the langref.
 * add operand type as first parameter
 * return type is ?T where T is the operand type

1999f0daad fix undefined behavior triggered by fn inline test
LLVM destroys the string that we use to test if LLVM deleted the
inlined function.

Also fixed forgetting to initialize a buffer in std lib path detection.

d26905c102 error return traces for the early return case

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.

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
