104b6f1629 refactored gen_h_file to improve maintainability and output
- extracted functions
- factorised extern "C" into a block containing all function prototypes instead of writing macros all over the place
- using intermediate buffers instead of writing directly to the output file

string literals are now null terminated
this also deletes C string literals from the language, and then makes
the std lib changes and compiler changes necessary to get the behavior
tests and std lib tests passing again.

rework layout of struct type fields
This removes the remaining hack in the implementation of anonymous
struct literals, and they can now therefore now have greater than 16
fields/elements.

introduce @as builtin for type coercion
This commit also hooks up type coercion (previously called implicit
casting) into the result location mechanism, and additionally hooks up
variable declarations, maintaining the property that:

    var a: T = b;

is semantically equivalent to:

    var a = @as(T, b);

synchronize the target features for compiling C code
d91fc0fdd8f42dc8c38347e1a0ec87fd583c1d3d changed zig's behavior to
disable the SSE feature when cross compiling for i386-freestanding.

This commit does the same when compiling C Code.

avoid passing -march=native when not supported
Clang does not support -march=native for all targets.
Arguably it should always work, but in reality it gives:
error: the clang compiler does not support '-march=native'
If we move CPU detection logic into Zig itelf, we will not need this,
instead we will always pass target features and CPU configuration explicitly.
For now, we simply avoid passing the flag when it is known to not be
supported.

move types from builtin to std
* All the data types from `@import("builtin")` are moved to
  `@import("std").builtin`. The target-related types are moved
  to `std.Target`. This allows the data types to have methods, such as
  `std.Target.current.isDarwin()`.
 * `std.os.windows.subsystem` is moved to
   `std.Target.current.subsystem`.
 * Remove the concept of the panic package from the compiler
   implementation. Instead, `std.builtin.panic` is always the panic
   function. It checks for `@hasDecl(@import("root"), "panic")`,
   or else provides a default implementation.

This is an important step for multibuilds (#3028). Without this change,
the types inside the builtin namespace look like different types, when
trying to merge builds with different target settings. With this change,
Zig can figure out that, e.g., `std.builtin.Os` (the enum type) from one
compilation and `std.builtin.Os` from another compilation are the same
type, even if the target OS value differs.

improve progress reporting
* use erase rest of line escape code.
 * use `stderr.supportsAnsiEscapeCodes` rather than `isTty`.
 * respect `--color off`
 * avoid unnecessary recursion
 * add `Progress.log`
 * disable the progress std lib test since it's noisy and uses
   `time.sleep()`.
 * enable/integrate progress printing with the default test runner
