  [libunwind][RISCV] Make asm statement volatile (#130286)

Compiling with `O3`, the `early-machinelicm` pass hoisted the asm
statement to a path that has been executed unconditionally during stack
unwinding. On hardware without vector extension support, this resulted
in reading a nonexistent register.
