the other changes in this commit are minor tidying up

Also added extra cache line
Added the ZigLVVMCreateTargetMachine to self hosted zig code

* 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.

See #903
* create with `@Vector(len, ElemType)`
* only wrapping addition is implemented
This feature is far from complete; this is only the beginning.

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.

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

This fixes a mismatched malloc/delete because
we were allocating with malloc and then llvm was
freeing with delete.
