error: LLVM ERROR: Unsupported expression in static initializer

Zig Version

0.11.0

Steps to Reproduce and Observed Behavior

the code is at https://github.com/girlbuzz/minos and if you simply build with zig build -Darch=x86 then you should get an error message that looks like this:

zig build-exe kernel.elf Debug x86-freestanding-none: error: LLVM ERROR: Unsupported expression in static initializer: or (i48 shl (i48 zext (i32 ptrtoint (ptr @arch.x86.gdt.gdt to i32) to i48), i48 16), i48 39)

zig build-exe kernel.elf Debug x86-freestanding-none: error: the following command terminated unexpectedly:

the related code seems to be this little line of code in src/arch/x86/gdt.zig

const gdtd = GDTDescriptor{
    .size = @sizeOf(@TypeOf(gdt)) - 1,
    .offset = &gdt,
};

when i set .offset to something like @ptrFromInt(0x1000) then it doesn't produce an error.

I was also able to reproduce the issue with just this code

minneelyyyy@DESKTOP-QJI9JDV:~$ zig build-exe b.zig
LLVM Emit Object... LLVM ERROR: Unsupported expression in static initializer: or (i80 shl (i80 zext (i64 ptrtoint (ptr @b.s to i64) to i80), i80 16), i80 3)
Aborted
minneelyyyy@DESKTOP-QJI9JDV:~$ cat b.zig
const std = @import("std");

const StringHolder = packed struct {
        length: u16,
        ptr: [*]const u8
};

const s = [_]u8 {'a', 'b', 'c'};

const sh = StringHolder{
        .length = 3,
        .ptr = &s
};

pub fn main() !void {
        // to ensure that sh is compiled in
        std.log.info("{}\n", .{sh.length});
}

Expected Behavior

Ideally this code would just compile, or if this isn't allowed for some reason, there should be a better error message produced by Zig itself and not an LLVM error.
