fix overflow found while fuzzing
...
* allow file level `union {}` to parse as tuple field
this was found while fuzzing zls.
* before this patch the input `union {}` crashed the parser. after
this, it parses correctly just like `struct {}`.
* adds behavior tests for both inputs `struct {}` and `union {}`,
checking that each becomes a file level tuple field.

std.zig: fix integer overflows during parsing
...
these were found while fuzzing zls.
this patch prevents overflow for the following file contents and adds
tests for them.
* `enum(u32)` - causes overflow in std.zig.Ast.fullContainerDecl()
* `*x` - causes overflow in std.zig.Ast.fullPtrType()
* `**x` - causes overflow in std.zig.Ast.firstToken()

remove most conditional compilation based on stage1

There are still a few occurrences of "stage1" in the standard library
and self-hosted compiler source, however, these instances need a bit
more careful inspection to ensure no breakage.

arm: move cpu model table into system/arm.zig
...
Now we can reuse the table between CPU model parsers on Linux and
Windows.
Use similar parsing structure for Windows as we do for Linux. On
Windows, we rely on two entries in the registry per CPU core:
`CP 4000` and `Identifier`. Collating the data from the two allows
us recreating most of the `/proc/cpuinfo` data natively on Windows.
Additionally, we still allow for overwriting any CPU features as flagged
by pulling the feature data embedded in `SharedUserData`.

Bug fix: Prevent uninitialized parse nodes

If a parse node is reserved but never set the node remains
uninitialized and can crash tools doing a linear scan of the nodes
(like ZLS) when switching on the tag.

Revert "x86" CPU model (not arch) back to "i386"
...
PR #13101 recently renamed the "i386" architecture to "x86", and it
seems the specific CPU model got swept up in that. "x86" is an umbrella
term that describes a family of CPUs, and the "i386" is the oldest
supported model under that umbrella.
