8d76c02f9a uefi: erroneous alignment check in pool_allocator 
Fixes #21446

Both UefiPoolAllocator and UefiRawPoolAllocator were
passing the value of `log2_ptr_align` directly to
`mem.alignAllocLen` which expects a alignment value.

Both of these calls to `mem.alignAllocLen` are pointless
and the result of the alignment both always true, and
was thrown away anyway.

I have removed these calls entirely.

ffd071f558 fix IB in fifoToOwnedArrayList 
memcpy requires non-overlapping arguments.

fifo.realign() handles this case correctly and tries to provide an
optimized implementation.

This probably wasn't hit in practice, as, in a typical usage, fifo's
head is not advanced.

Improve efficiency of buffered_reader. (#21256) 
The previous implementation of buffered_reader always reads from the
unbuffered reader into the internal buffer, and then dumps the data onto
the destination. This is inefficient, as sometimes it's possible to read
directly into the destination. The previous strategy generates more
memory copies and unbuffered reads than necessary.

d1901c744c std.Target: Remove Cpu.Arch.dxil and ObjectFormat.dxcontainer. 
See: https://devblogs.microsoft.com/directx/directx-adopting-spir-v

Since we never hooked up the (experimental) DirectX LLVM backend, we've never
actually supported targeting DXIL in Zig. With Microsoft moving away from DXIL,
that seems very unlikely to change.

509639717a std.equalRange: Compute lower and upper bounds simultaneously 
The current implementation of `equalRange` just calls `lowerRange` and `upperRange`, but a lot of
the work done by these two functions can be shared. Specifically, each iteration gives information about whether the lower bound or the upper bound can be tightened. This leads to fewer iterations and, since there is one comparison per iteration, fewer comparisons.
Implementation adapted from [GCC](519ec1cfe9/libstdc%2B%2B-v3/include/bits/stl_algo.h (L2063)).
This sample demonstrates the difference between the current implementation and mine:

```zig
fn S(comptime T: type) type {
    return struct {
        needle: T,
        count: *usize,

        pub fn order(context: @This(), item: T) std.math.Order {
            context.count.* += 1;
            return std.math.order(item, context.needle);
        }
        pub fn orderLength(context: @This(), item: []const u8) std.math.Order {
            context.count.* += 1;
            return std.math.order(item.len, context.needle);
        }
    };
}
pub fn main() !void {
    var count: usize = 0;

    try std.testing.expectEqual(.{ 0, 0 }, equalRange(i32, &[_]i32{}, S(i32){ .needle = 0, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 0, 0 }, equalRange(i32, &[_]i32{ 2, 4, 8, 16, 32, 64 }, S(i32){ .needle = 0, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 0, 1 }, equalRange(i32, &[_]i32{ 2, 4, 8, 16, 32, 64 }, S(i32){ .needle = 2, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 2, 2 }, equalRange(i32, &[_]i32{ 2, 4, 8, 16, 32, 64 }, S(i32){ .needle = 5, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 2, 3 }, equalRange(i32, &[_]i32{ 2, 4, 8, 16, 32, 64 }, S(i32){ .needle = 8, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 5, 6 }, equalRange(i32, &[_]i32{ 2, 4, 8, 16, 32, 64 }, S(i32){ .needle = 64, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 6, 6 }, equalRange(i32, &[_]i32{ 2, 4, 8, 16, 32, 64 }, S(i32){ .needle = 100, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 2, 6 }, equalRange(i32, &[_]i32{ 2, 4, 8, 8, 8, 8, 15, 22 }, S(i32){ .needle = 8, .count = &count }, S(i32).order));
    try std.testing.expectEqual(.{ 2, 2 }, equalRange(u32, &[_]u32{ 2, 4, 8, 16, 32, 64 }, S(u32){ .needle = 5, .count = &count }, S(u32).order));
    try std.testing.expectEqual(.{ 1, 1 }, equalRange(f32, &[_]f32{ -54.2, -26.7, 0.0, 56.55, 100.1, 322.0 }, S(f32){ .needle = -33.4, .count = &count }, S(f32).order));
    try std.testing.expectEqual(.{ 3, 5 }, equalRange(
        []const u8,
        &[_][]const u8{ "Mars", "Venus", "Earth", "Saturn", "Uranus", "Mercury", "Jupiter", "Neptune" },
        S(usize){ .needle = 6, .count = &count },
        S(usize).orderLength,
    ));

    std.debug.print("Count: {}\n", .{count});
}
```
For each comparison, we bump the count. With the current implementation, we get 57 comparisons. With mine, we get 43.

With contributions from @Olvilock.
This is my second attempt at this, since I messed up the [first one](https://github.com/ziglang/zig/pull/21290).
