[BOLT][AArch64] Optimize the mov-imm-to-reg operation (#189304)
On AArch64, logical immediate instructions are used to encode some
special immediate values. And even at `-O0` level, the AArch64 backend
would not choose to generate 4 instructions (movz, movk, movk, movk) for
moving such a special value to a 64-bit regiter.
For example, to move the 64-bit value `0x0001000100010001` to `x0`, the
AArch64 backend would not choose a 4-instruction-sequence like
```
movz x0, 0x0001
movk x0, 0x0001, lsl 16
movk x0, 0x0001, lsl 32
movk x0, 0x0001, lsl 48
```
Actually, the AArch64 backend would choose to generate one instruction
```
mov x0, 0x0001000100010001
```

[LV] Update remaining tests to use VPlan cost output (NFC). (#190038)
Move remaining tests checking legacy cost output to check the VPlan's
cost model output.
In some cases, checks become much more compact (checking a single
interleave group cost vs checking the individual members which all have
the group's cost). In some cases, auto-generation consistently checks
all relevant VFs.

[CIR] Add support for variable sized array new. (#190656)
This change adds support for array new with variable size. This required
extending the cir.array.ctor operation to accept a value for the size
and a direct pointer to the element size instead of a pointer to an
array.

sysutils/uutils-coreutils: import package
uutils coreutils is a cross-platform reimplementation of the GNU coreutils in
Rust. While all programs have been implemented, some options might be missing
or different behavior might be experienced.
This project aims to be a drop-in replacement for the GNU utils. Differences
with GNU are treated as bugs.
uutils aims to work on as many platforms as possible, to be able to use the
same utils on Linux, Mac, Windows and other platforms. This ensures, for
example, that scripts can be easily transferred between platforms.
