* stage2: Make zig cc more verbose
Make `zig cc` print more info from Clang itself and from our own linker
invocation, this is needed for CMake to properly discover all the
include directories and library search paths.
Closes#7110
* Update `update_clang_options`
* Typo fixes

Master branch renamed an enum; this branch gave it an explicit tag type
and explicitly initialized values. This commit combines the changes
together.
This cleans up how the CLI parses and handles -E, -S, and -c.
Compilation explicitly acknowledges when it is being used to do C
preprocessing.
-S is properly translated to -fno-emit-bin -femit-asm but Compilation
does not yet handle -femit-asm.
There is not yet a mechanism for skipping the linking step when there is
only a single object file, and so to make this work we have to do a file
copy in link.flush() to copy the file from zig-cache into the output
directory.
