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.

9bb76f8ce0 Use correct compiler flags in MSVC bootstrap builds of Zig 
https://github.com/ziglang/zig/issues/4877

The CMake build of Zig from C++ uses hand-set compiler flags which are
not compatible with the Microsoft C/C++ Optimizing Compiler (cl.exe)
used by Visual Studio.

This commit attempts to conform them to match the Clang/GCC options
under MSVC builds.

Note that CL does not have a concept of C99 or "-O3", and may imply
other optimizations in "/O2" than are implied by Clang/GCC "-O3".

Visual Studio 2019 documentation for cl.exe's optimization options:
https://docs.microsoft.com/en-us/cpp/build/reference/o-options-optimize-code?view=vs-2019

Visual Studio 2019 doc for cl.exe's C++ standard options:

revert detection of rtti and exceptions 
This caused link errors in c++ code because it was not correct to pass
these flags to child codegens. And that was the only reason to detect
these flags. Otherwise we can safely rely on non-explicitly-detected
flag forwarding.

linking: remove check for target_supports_libunwind 
I'm not sure why this was ever there. Maybe it was working around a

arm and riscv.

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
