[PATCH] D68011: [RISCV] Split SP adjustment to reduce the offset of callee saved register spill and restore

[Luís Marques via Phabricator via llvm-commits]

luismarques added a comment.

`getFirstSPAdjustAmount` does a non-trivial amount of work. Instead of calling it repeatedly it would be better to call it once per prologue/epilogue generation, and cache the result in a local variable.
With that fixed it LGTM.
