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.

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.
