This is a NFC patch.
This patch run a bulk update on CodeGen tests that are impacted by the
true16 features. This patch applies:
1. duplicate GFX11plus runlines and apply them with
"+mattr=+real-true16" and "+mattr=-real-true16"
2. update the test with the update script
For some GISEL runlines, the current CodeGen do not fully support the
true16 version. Still update the runlines, but comment out the failing
one, and added a "FIXME-TRUE16" comment to that test for easier
tracking. These test will be fixed in the following patches.
This is in a transition state that we support both
"+real-true16/-real-true16" in our code base. We plan to move to
"+real-true16" as default, and finally remove "-real-true16" mode and
test lines.
`RegisterClassInfo::getRegPressureSetLimit` is a wrapper of
`TargetRegisterInfo::getRegPressureSetLimit` with some logics to
adjust the limit by removing reserved registers.
It seems that we shouldn't use
`TargetRegisterInfo::getRegPressureSetLimit`
directly, just like the comment "This limit must be adjusted
dynamically for reserved registers" said.

Mark these intrinsics as atomic loads within LLVM to prevent hoisting
out of loops in cases where
the load is considered invariant.
Similar to https://github.com/llvm/llvm-project/pull/97707, but for
struct buffer loads.
