recog: Add an RAII class for undoing insn changes
When using validate_change to make a group of changes, you have
to remember to cancel them if something goes wrong. This patch
adds an RAII class to make that easier. See the comments in the
patch for details and examples.
gcc/
* recog.h (insn_change_watermark): New class.
