linux-user/loongarch64: Decode BRK break codes for FPE signals
Handle specific LoongArch BRK break codes in user-mode emulation
to deliver accurate floating-point exception signals. Specifically,
BRK_OVERFLOW (6) triggers TARGET_FPE_INTOVF, and BRK_DIVZERO (7)
triggers TARGET_FPE_INTDIV. Other BRK codes fall back to a generic
SIGTRAP.
This improves correctness for programs that rely on BRK to signal
overflow or divide-by-zero conditions.
