[RFA] Update ARM attribute support for v2.08 of the ABI for the ARM Architecture

[Matthew Gretton-Dann]

All,

Please can someone review and approve the attached patch?

This updates binutils to support the changes in attributes made in v2.08
of the ABI for the ARM Architecture.

In particular this includes:
 * Renaming of several attribute tags - although the old names are still
recognised.
 * Extending recognised values for Tag_ABI_align_needed,
Tag_ABI_align_preserved, and Tag_Virtualization_use.
