a284be3f69 Fix unsafe cast in translate_c

std.Target.CpuFeatures is now a struct with both CPU and feature set
Previously it was a tagged union which was one of:
 * baseline
 * a specific CPU
 * a set of features

Now, it's possible to have a CPU but also modify the CPU's feature set
on top of that. This is closer to what LLVM does.

This is more correct because Zig's notion of CPUs (and LLVM's) is not
exact CPU models. For example "skylake" is not one very specific model;
there are several different pieces of hardware that match "skylake" that
have different feature sets enabled.

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.
