[SPARC] Expand f64 bitcasts from v2i32 on 32-bit SPARC (#234201)
It is not possible to directly transfer values from integer registers to
floating point registers, so it needs to be done via the stack.
Fixes the following error:
LLVM ERROR: Cannot select: t10: f64 = bitcast t16
t16: v2i32 = BUILD_VECTOR t2, t4
t2: i32,ch = CopyFromReg t0, Register:i32 %0
t4: i32,ch = CopyFromReg t0, Register:i32 %1
In function: v2i32_build_vector

[SPARC] Preserve register operand flags in BPR branch conditions (#240077)
parseCondBranch() rebuilt the register operand of a branch-on-register
(BPR) instruction from just its register number, and insertBranch()
re-added it with addReg(), so any operand flags were lost when a branch
was analyzed and reinserted.
When the register is undef (ProcessImplicitDefs marks the use undef
after removing its IMPLICIT_DEF), PHI elimination splitting a critical
edge rewrites the terminator via updateTerminator() and the BPR ends up
reading a virtual register with no def. The machine verifier rejects
this, and without the verifier the greedy register allocator segfaults
in VirtRegAuxInfo::weightCalcHelper.
Copy the whole MachineOperand into Cond and add it back with add(), as
other targets do.
Fixes #233111

arm64 pmap: demote L3C pages in pmap_clear_modify()
When pmap_clear_modify() demotes a dirty L2 block mapping, it write
protects the L3 entry that maps "m", so that a subsequent write access
may repromote. However, since fd6cb031f577, the L3 entries created by
pmap_demote_l2_locked() may have ATTR_CONTIGUOUS set, and
pmap_clear_modify() was write protecting one L3 entry within an L3C page
while leaving the page's other L3 entries writeable with ATTR_CONTIGUOUS
still set. A TLB entry that a processor creates from any of those other
L3 entries may translate "m"'s virtual address and permit writes to "m"
without a fault. To fix this issue, as in pmap_remove_write(), demote
the L3C page before write protecting the L3 entry.

[NVPTX] Select scalar_to_vector for bf16x2 (#236706)
Fixes #235368.
DAG combining can create a v2bf16 SCALAR_TO_VECTOR for byte-vector
concatenations, including copies of unaligned bfloat values through
local arrays. NVPTX treats the node as legal but lacks a selection
pattern.
Pack the bf16 value into the low half of a 32-bit register and zero the
unspecified high half, as already done for v2f16. Add regression
coverage for direct packing, unaligned loads, and the original
local-array copy.
