Recognize hard-float variant of ARM's EABI (as in RTABI)

[Joerg Sonnenberger]

Hi all,
the attached patch adds support for *-eabihf, which uses ARM_AAPCS_VFP
as calling convention in combination with the __aeabi_* library
functions. The only non-trivial part of the patch is in Clang where the
change to isEABI() will make getSizeOfUnwindException() return 88 for
GNUEABIHF as it would for GNUEABI. I'm not sure if the difference is
intentional -- it doesn't make sense to me. Comments?
