Log message:
Help the DWARF code to handle our prologues correctly:
- add the frame pointer to EPILOGUE_USES when profiling
- when the initial stack adjustement is larger than 64KB and requires a
temporary register to be used, add a REG_FRAME_RELATED_EXPR of the original
computation (not constrained by the adjustement size) to the REG_NOTES of
the stack pointer adjustement sequence. Borrowed from alpha which has a
similar issue.
