Fix expected stack allocation size for aarch64 with LLVM 22.1.8.
LLVM 22.1.8 optimizes non-overlapping scope stack reuse more
aggressively (32 bytes instead of 48). This test is new in 1.97.0
and was validated against bundled LLVM 22.1.6.

+ aarch64 with LLVM 22.1.8
+
+LLVM 22.1.8 optimizes stack allocation more aggressively for
+non-overlapping scopes on aarch64. For scoped_two_small_structs,
+it produces 'sub sp, sp, #32' instead of #48, because 2 non-overlapping
+16-byte structs can share a 32-byte allocation. The three-struct version
+still requires #48.

+Upstream-Status: Inappropriate [OE-specific, LLVM version difference]
Hello Sundeep,
the update is okay, except this patch's commit message: it should have
an explanation of if/when the patch can be removed, and/or an upstream
ticket that notifies upstream of the issue. These things are generally
expected of 'Inappropriate' patches.
Hello Alex,
There a bugfix release 1.97.1. We will be sending that upgrade and this
will be fixed there.
Thanks,
Sundeep K.
Alex
