clean up arm CPU features 
* remove "cpu features" that are actually just processors
 * rename `v8` to `v8a`. this matches the corresponding
   change to target/aarch64.zig
 * rename types in preparation for removing sub-architecture
   from `std.Target`.

I have other files changed in my dirty working tree, but about to make
some changes to arm.zig that I don't want batched with this commit.

make the CLI support depending on system headers and libraries 
(include and lib search paths)

The detection of native system paths is self-hosted.

improvements which allow zig to emit multiple things at once 
example: zig build-obj test.zig -femit-llvm-ir -femit-asm

this will generate all three: test.o test.s test.ll

Makes the declaration slice resolve lazely when using @typeInfo 
This way all the declarations in a container won't be resolved untill
the user actually uses the decls slice in the builtin TypeInfo union.

smarter detectNativeDynamicLinker logic 
The current target's ABI cannot be relied on for this.
For example, we may build the zig compiler for target
riscv64-linux-musl and provide a tarball for users to
download. A user could then run that zig compiler on
riscv64-linux-gnu. This use case is well-defined and
supported by Zig. But that means that we must detect
the system ABI here rather than
relying on `std.Target.current`.

expand argv[0] when spawning system C compiler 
Some C compilers, such as Clang, are known to rely on
argv[0] to find the path to their own executable,
without even bothering to resolve PATH. This results
in the message:

error: unable to execute command: Executable "" doesn't exist!

So we tell ChildProcess to expand argv[0] to the absolute path
to give them a helping hand.

stage1: don't copy unchanged output files 
when both `--cache on` and `--output-dir` parameters
are provided. This prevents re-linking `zig` with every

remove libc dependency of zig0 building libstage2 
Rather than `zig0 build ...` the build now does
`zig0 build-lib ...`, avoiding the requirement of linking the build
script, and thus avoiding the requirement of finding native libc,
for systems where libc is the system ABI.
