stage1: Fix bitcast of immediate to ptr type (#5131) 
Consider a (legal according to the `@bitCast` rules) conversion from u16
to [2]u8: since the former is a scalar and the latter is a pointer
(arrays are represented at pointers in the codegen phase) we have to
allocate a temporary slot on the stack and then bitcast the resulting
pointer to the desired destination type.

Beware that this means the lifetime of the resulting value is the same
of the function it's contained in and for all intents and purposes
should be regarded as a local (eg. it should not escape).

Closes #4395
Closes #5121

Changing the pointer length from Unknown to Single/C now resets the
sentinel value too.

212e2354b8 stage1: make C++ switch fallthrough an error 
Make fallthrough an error when compiler supports it. This requires a new
macro that is defined with such compilers to be used as a statement, at
all fallthrough sites:

    switch (...) {
        case 0:
            ...
            ZIG_FALLTHROUGH;
        case 1:
            ...
            break;
        default:
            ...
            break;
    }

If we ever move to C++17 as minimal requirement, then the macro can be
replaced with `[[fallthrough]];` at statement sites.

d33766e6c7 Make sure that ZigTypeVector and ZigTypeArray have the same memory layout 
Throughout the stage1 code it is assumed that these have the same layout,
but that was not the case. This caused an issue on 32-bit hardware.

add peer type resolution for mixed-const []T and *[N]T 
closes #4766

This commit also fixes the implementation of some utility functions for
adjusting properties of pointer types. Previously these functions would
incorrectly drop vector, sentinel, and inference metadata.

c1cc1ebc35 ir: Avoid constant-folding ptr to sentinels 
Constant-folding the pointers to the expected sentinel value have some
big problems: it hides the real content of the array, makes the pointer
to the sentinel point to a completely different memory region and treats
it like a const value even when the underlying array is mutable.

Fixes #4840
