2f465761bb stage1: Implement @intCast between vectors 
Explicit and implicit integer casts on vector types are now supported
and follow the same rules as their scalar counterparts.

Implicit float casts are accidentally supported, `@floatCast` is still
not vector-aware.

b6556c944b fix another round of regressions in this branch 
* std.log: still print error messages in ReleaseSmall builds.
   - when start code gets an error code from main, it uses std.log.err
     to report the error. this resulted in a test failure because
     ReleaseSmall wasn't printing `error: TheErrorCode` when an error
     was returned from main. But that seems like it should keep working.
     So I changed the std.log defaults. I plan to follow this up with a
     proposal to change the names of and reduce the quantity of the
     log levels.
 * warning emitted when using -femit-h when using stage1 backend; fatal
   log message when using -femit-h with self-hosted backend (because the
   feature is not yet available)
 * fix double `test-cli` build steps in zig's build.zig
 * update docgen to use new CLI
 * translate-c uses `-x c` and generates a temporary basename with a
   `.h` extension. Otherwise clang reports an error.
 * --show-builtin implies -fno-emit-bin
 * restore the compile error for using an extern "c" function without
   putting -lc on the build line. we have to know about the libc
   dependency up front.
 * Fix ReleaseFast and ReleaseSmall getting swapped when passing the
   value to the stage1 backend.
 * correct the zig0 CLI usage text.
 * update test harness code to the new CLI.

2cd19c05d0 stage1: remove buggy "unable to inline function" compile error 
We still want this compile error but I'm giving up on implementing it
correctly in stage1. It's been buggy and has false positives sometimes.

I left the test cases there, but commented out, so that when we go
through the stage1 compile error cases and get coverage for them in
stage2 we can reactivate the test cases.

d3ebd42865 Support taking extern pointers at comptime 
This commit makes it possible to obtain pointers to `extern` variables
at comptime.

 - `ir_get_var_ptr` employs several checks to determine if the given
   variable is eligible for obtaining its pointer at comptime. This
   commit alters these checks to consider `extern` variables, which have
   runtime values, as eligible.

 - After this change, it's now possible for `render_const_val` to be
   called for `extern` variables. This commit modifies
   `render_const_val` to suppress the value generation for `extern`
   variables.

 - `do_code_gen` now creates `ZigValue::llvm_global` of `extern`
   variables before iterating through module-level variables so that
   other module-level variables can refer to them.

This solution is incomplete since there are several cases still
failing:

 - `global_var.array[n..m]`
 - `&global_var.array[i]`
 - `&global_var.inner_struct.value`
 - `&global_array[i]`

separate std.Target and std.zig.CrossTarget 
Zig now supports a more fine-grained sense of what is native and what is
not. Some examples:

This is now allowed:
-target native

Different OS but native CPU, default Windows C ABI:
-target native-windows
This could be useful for example when running in Wine.

Different CPU but native OS, native C ABI.
-target x86_64-native -mcpu=skylake

Different C ABI but otherwise native target:
-target native-native-musl
-target native-native-gnu

Lots of breaking changes to related std lib APIs.
Calls to getOs() will need to be changed to getOsTag().
Calls to getArch() will need to be changed to getCpuArch().

Usage of Target.Cross and Target.Native need to be updated to use
CrossTarget API.

`std.build.Builder.standardTargetOptions` is changed to accept its
parameters as a struct with default values. It now has the ability to
specify a whitelist of targets allowed, as well as the default target.
Rather than two different ways of collecting the target, it's now always
a string that is validated, and prints helpful diagnostics for invalid
targets. This feature should now be actually useful, and contributions
welcome to further improve the user experience.

`std.build.LibExeObjStep.setTheTarget` is removed.
`std.build.LibExeObjStep.setTarget` is updated to take a CrossTarget
parameter.

`std.build.LibExeObjStep.setTargetGLibC` is removed. glibc versions are
handled in the CrossTarget API and can be specified with the `-target`
triple.

`std.builtin.Version` gains a `format` method.
