be9841335e std.Target.Os: Rename lv2 to ps3. 
It is very non-obvious that this is what lv2 refers to, and we already use ps4
and ps5 to refer to the later models, so let's just be consistent.

db8bc4770c std.Target: Remove the tce/tcele arch tags. 
There is no obvious reason why this would be relevant for Zig to target. I
rather question the value of LLVM even having target triple code for this, too.

21cc5a2044 std.Target: Remove the shave arch tag. 
This was added as an architecture to LLVM's target triple parser and the Clang
driver in 2015. No backend ever materialized as far as I can see (same for GCC).
In 2016, other code referring to it started using "Myriad" instead. Ultimately,
all code related to it that isn't in the target triple parser was removed. It
seems to be a real product, just... literally no one seems to know anything
about the ISA. I figure after almost a decade with no public ISA documentation
to speak of, and no LLVM backend to reference, it's probably safe to assume that
we're not going to learn much about this ISA, making it useless for Zig.

67a052df81 std.Target: Remove amdil/amdil64 arch tags. 
This is really obscure and no one is 100% sure what it is. It seems to be old
and unused. My suspicion is that it's just an old term for "AMDGPU" before it
was upstreamed to LLVM.

c825b567b2 std.Target: Remove the r600 arch tag. 
These are quite old GPUs, and it is unlikely that Zig will ever be able to
target them.

9939b116bf std.Target: Remove the gnuf64 ABI specifier. 
This was used for LoongArch64, where:

* `gnuf64` -> `ilp32d` / `lp64d` (full hard float)
* `gnuf32` -> `ilp32f` / `lp64f` (hard float for `f32` only)
* `gnusf` -> `ilp32` / `lp64` (soft float)

But Loongson eventually settled on just `gnu` for the first case since that's
what most people will actually be targeting outside embedded scenarios. The
`gnuf32` and `gnusf` specifiers remain in use.

94cf4d2d81 llvm: add pass-by-reference info to debug types 
Without this data, debugger expressions try to pass structs by-value,
which mostly just crashes.
Also: mark enums as enum classes to prevent the enumerators from
shadowing other identifiers.

177b3359a1 llvm: Do not generate static member definitions 
They were not helping LLDB and actively throwing off GDB.

longer necessary.

52e4cdb45e Try linking static members' definitions to their declarations. 
This does not help anything though: gdb would follow the
DW_AT_specification link only in the opposite direction, which LLVM
cannot emit.

359bbdd574 llvm: encode variables as DW_TAG_imported_declaration 
Now we get working global variable lookup in GDB! LLDB still re-mangles,
and it looks like we can't do much about that for now.

Also: translate non-owning type declarations into typedefs.

876258abe4 llvm: set precise scopes on namespace types and variables 
This will allow accessing non-local declarations from debuggers, which,
AFAICT, was impossible before.
Getting scopes right already works for type declarations and functions,
but will need some fiddling for variables:

For those, I tried imitating what Clang does for static member
variables, but LLDB tries to re-mangle those and then fails at lookup,
while GDB outright crashes. Hopefully I can find some other dwarven
incantation to do the right thing.
