f8fe517d12 better string literal caching implementation 
We were caching the ConstExprValue of string literals,
which works if you can never modify ConstExprValues.
This premise is broken with `comptime var ...`.

So I implemented an optimization in ConstExprValue
arrays, where it stores a `Buf *` directly rather
than an array of ConstExprValues for the elements,
and then similar to array of undefined, it is
expanded into the canonical form when necessary.
However many operations can happen directly on the
`Buf *`, which is faster.

Furthermore, before a ConstExprValue array is expanded
into canonical form, it removes itself from the string
literal cache. This fixes the issue, because before an
array element is modified it would have to be expanded.

32be6e9b2a caching is working 
* add almost all the input parameter state to the hash
   - missing items are the detected MSVC installation on Windows
     and detected libc installation on POSIX
   - also missing are C files and .h files that libclang finds
 * artifacts are created in global cache directory instead of
   zig-cache.
   - exception: builtin.zig is still in zig-cache
 * zig run uses the new cache correctly
 * zig run uses execv on posix systems
