* CLI: `-target [name]` instead of `--target-*` args.
This matches clang's API.
* `builtin.Environ` renamed to `builtin.Abi`
- likewise `builtin.environ` renamed to `builtin.abi`
* stop hiding the concept of sub-arch. closes#1526
* `zig targets` only shows available targets. closes#438
* include all targets in readme, even those that don't
print with `zig targets` but note they are Tier 4
* refactor target.cpp and make the naming conventions
more consistent
* introduce the concept of a "default C ABI" for a given
OS/Arch combo. As a rule of thumb, if the system compiler
is clang or gcc then the default C ABI is the gnu ABI.
Prevents LLVM from generating debug info for
struct member functions with a pointer as the
first parameter as though the first parameter
were the implicit "this" pointer from C++.
it has a patch that adds an OS type, breaking the public API
this commit avoids depending on the last os type enum item,
but retains the safety assertion checks.
closes#1788
On Arch Linux the current default compiler is gcc 8.2.1 and this change
is needed to ignore the following errors:

Add wasm32 support to the build-obj, build-exe and build-lib commands
of the stage 1 compiler. Wasm64 should work transparently once it's
supported in upstream LLVM.
To export a function:
// lib.zig - for exposition, not necessary for this example
pub use @import("add.zig");
// add.zig
export fn add(a: i32, b: i32) i32 {
return a + b;
}
To import a function:
// cube.zig
extern fn square(x: i32) i32;
export fn cube(x: i32) i32 {
return x * square(x);
}
* 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
