This patch encapsulates the check for wether a `SUnit` is clustered,

only a single user, but more users can show up, and I think it provides
a cleaner API even for that single user.

[analyzer] Refine default binding preservation in RegionStore (#189319)

Narrow the new setImplicitDefaultValue() guard so existing default
bindings are preserved only for aggregate-like cases.

The previous change was too broad and regressed normal
zero-initialization, causing new int[10]{} to be modeled as undefined
and emit a garbage-value warning instead of the expected analyzer
reports.

[AArch64] Skip non-pseudo instructions in AArch64ExpandPseudoInsts (#191395)

AArch64::getSVEPseudoMap calls are visible in compile-time profiles even on
non-SVE targets. I think CodeGenMapTable could be improved, it's currently
emitting a constexpr array sorted by opcode and a hand-rolled binary search
over that array, however the AArch64ExpandPseudoInsts pass is missing a simple
check for pseudo instructions before expanding. This avoids the compile-time
cost.
