[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.

ppp: bound Predictor-1 decompression output
Pred1Input() decompressed CCP data into a MAX_MRU+2 mbuf with no limit
on the output, so a peer could expand a short compressed frame (up to
8:1) past the buffer and overflow adjacent heap. An input length below
4 also drove decompress() with a negative length.
Reject out-of-range input lengths and stop decompression at the
destination buffer size.

ppp: drop config packets whose options overrun the packet
fsm_readopt() advanced the decode cursor by the option length without
checking it against the end of the packet. A crafted LCP/CCP/IPCP
option could then make the Config-Reject/Nak echo copy past the
received packet into adjacent heap, disclosing heap bytes to the peer
before authentication.
Check the option framing once in fsm_Input() and drop the packet before
decoding per RFC1661

linux: do not truncate the listxattr() size
listxattr() sized its buffer with min(), which truncates the 64-bit
size to 32 bits, so a size of 2^32 + k allocated k bytes while the
copy-out guard used the full size. The walk then read record lengths
past the buffer and copied kernel heap out to the caller, and could
panic the kernel. Any user can reach it through a user.* attribute on
a file it owns.
Use MIN(), and fail with EIO if a record runs past the data returned.
