add compile error for casting const array to mutable slice

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.

remove `zig build --init`. add `zig init-lib` and `zig init-exe`
init-lib creates a working static library with tests, and
init-exe creates a working hello world with a `run` target.

both now have test coverage with the new "cli tests" file.

fix incorrect error union const value generation
closes #1442

zig needed to insert explicit padding into this structure before
it got bitcasted.

fix incorrect union const value generation
closes #1381

The union was generated as a 3 byte struct when it needed to be
4 bytes so that the packed struct bitcast could work correctly.

Now it recognizes this situation and adds padding bytes to become
the correct size so that it can fit into an array.
