Shift error message now says "fixed-width integer type" instead of just "integer type" (#5028) 
* error message of ir_analyze_bit_shift now more accurate/specific

* fixed compile error test to match bit shift error message

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

partial revert of an improvement this branch made 
because it uncovered a result location bug, and I need to get this
branch merged before going into a result location rabbit hole.

also fix the result type of slicing when the indexes are runtime known
and the result should be sentinel terminated.
