[Patch ARM] Fix dwarf2cfi_asm properly.

[Ramana Radhakrishnan]

Hi,

I just realized that I'd (sent out and) committed the wrong version of
the patch for working around the dwarf2cfi_asm problem, in which I was
checking for TARGET_AAPCS_BASED before arm_abi was initialized !  

Thanks to Kirrill for pointing it out that it was not working correctly.

I've now committed the following fix as obvious r152446 and will
backport this to the 4.4 branch as well.

[I also took the opportunity of fixing a problem with the previous
Changelog entry on trunk.]


cheers
Ramana
