Is there something specific in 4.7 you are waiting for?  4.6 is probably
good enough -- it has the biggest improvement (VTA -- first in 4.5) plus
a few more -- but I don't know of anything so major that would advise
skipping 4.6.

In practice I build gdb with -O0 when I want to debug.  Occasionally I
just rebuild a single .o this way.  VTA is good, but when debugging I
care about 100% visibility into the source and nearly zero about
performance.
