Different outputs in Gimple pass dump generated by two different architectures

[Kevin Lee]

Hello GCC,

 While looking at the failure for gcc.dg/uninit-pred-9_b.c, I observed that
x86-64 and risc-v has a different output for the gimple pass since
r12-4790-g4b3a325f07acebf4
. What
would be causing the difference? Is this intended?
Link  for details. Thank you!

Sincerely,
Kevin

This PR was a great explanation for the macro. Thanks!
