b91eaba38c Correct evaluation of optional type alignment 
The lazy logic was too oversimplified and produced a different result
than the one computed later causing all kinds of problems.

Closes #4013

1e61e5f404 Don't ptrCast a result-location assignment to _

translate-c: improve support of integer casting 
Widening and truncating integer casting to different signedness
works better now. For example `(unsigned long)-1` is now translated
to zig code that compiles correctly.

translate-c: better mangling strategy 
Block-local identifiers have block-local mangling numbers, and more
consistent mangling is applied within blocks. Parameters, for example,
are treated the same as other block-local variables, and are not mangled
unless they conflict with another name in scope.

translate-c: non-wrapping operator for pointer arithmetic 
According to C11 6.5.6.8, pointer arithmetic may not overflow. In fact,
it may not even go more than 1 past the end of an object, or UB occurs.

This is the same as Zig pointer arithmetic semantics, and so the
`+` and `+=` operators rather than `+%` and `+%=` are appropriate for
C-translated pointer arithmetic.

sentinel slicing improvements 
* add runtime safety for slicing pointers, arrays, and slices.
 * slicing without a sentinel value results in non-sentineled slice
 * improved `std.debug.panic` handling of panic-during-panic
