34e9bbb9d4 enable the LLVM backend in stage2 
This takes a bit longer since the interpreted part has to do more work
but it saves a round trip through the compiler by allowing `zig2 build`
to be the final step. 1-2-3, done.

For me this is currently failing due to compilation errors generated by
GCC when compiling zig2.c but in theory if those are fixed, it should
work!

39fd77bc16 interpret the WASI blob to produce zig2.c and compiler_rt.c 
* synchronize zig1.c from zig-wasi external project
 * change the way argv works to avoid absolute paths
 * autodetect isatty
 * compiler_rt: disable some functions when object format is C
 * add missing flag from config.zig.in

The next problem is that compiling compiler_rt.c with gcc gives
"conflicting types" errors for `__eqhf2` and friends.

ef447c3eca redo CMakeLists.txt to use WASI interpreter 
current status is that it hits error: OutOfMemory for unknown reasons,
probably due to bugs in the C WASI interpreter port.
