Subject: [patch] two more bitmap obstacks

Hello,

Two more bitmap obstacks, this time in tree-ssa-coalesce.c.

The advantage isn't so much in having the bitmaps on the non-default
obstack, but more in that the bitmaps can be free'ed all at once by
simply releasing the obstack.

Bootstrapped&tested on x86_64-unknown-linux-gnu. OK for trunk?

Ciao!
Steven
