wangmingrong1 51a82d5289 arm/clang: Fix crash caused by clang compiling with -mfpu=fpv5-d16 and -march=armv8.1-m.main+mve.fp+fp.dp 
The above combination of compilation causes the compiler to crash:
 #1 0x0000000001fbe154 llvm::sys::CleanupOnSignal(unsigned long) (clang18/bin/clang-19+0x1fbe154)
 #2 0x0000000001f21203 llvm::CrashRecoveryContext::HandleExit(int) (clang18/bin/clang-19+0x1f21203)
 #3 0x0000000001fb7b7e llvm::sys::Process::Exit(int, bool) (clang18/bin/clang-19+0x1fb7b7e)
 #4 0x0000000000b25f0d (clang18/bin/clang-19+0xb25f0d)
................................................................................
................................................................................
This problem occurs in clang18 and above, and there are compilation instructions that are incompatible with GCC.
By following the recommended v8.1m corresponding fpu modification, no crash will occur
