D154931[1] needs to be reverted on LLVM17. As Loongson SIMD Extension
(LSX) and Loongson Advanced SIMD Extension(LASX) are not fully
supported on LLVM17, InlineAsm for LSX and LASX should not be
supported as well. Otherwise it leads to the following issue[2]:
'''
LLVM ERROR: Cannot select: 0x7ffea41a3650: ch = store<(store (s128) into %ir.mask
store52)> 0x7ffea41a35e0, 0x7ffea4196a30, FrameIndex:i64<6>, undef:i64
'''
LSX and LASX are fully supported on LLVM18 and are not supported on LLVM16,
thus only LLVM17 has the problem.

> dh_install: warning: Cannot find (any matches for) "usr/lib/llvm-17/lib/clang/17/bin/hwasan_symbolize" (tried in ., debian/tmp)
hwasan_symbolize is actually an 64-bit-only feature, and was
accidentally included before. Replace the arch opt-out list, with an
opt-in one and a comment pointing to HWASAN_SUPPORTED_ARCH.
> dh_install: warning: Cannot find (any matches for) "usr/lib/llvm-17/lib/clang/17*/lib/linux/liborc_rt*" (tried in ., debian/tmp)
i386 is not in the ALL_ORC_SUPPORTED_ARCH list. Previously, the package
shipped liborc_rt-x86_64.a, but since we don't ship amd64 multilib
binaries anymore, remove the reference.

This was despite an upstream commit labeled "[compiler-rt] support
armv4t". Perhaps something going on with the way we configure? Revert
for the time being, until (if) someone cares.
This reverts commit 1b0abffef7.
