* Committed fix for LP #968766 (PR tree-optimization/52880)
to FSF mainline and Linaro GCC 4.6 and 4.7.
* Created merge reqest to fix LP #972648 for Linaro GCC 4.6
by backporting mainline patch; pending approval.
* Updated patch to use vld1.64/vst1.64 instead of vldm/vstm
Add --no-use-blx switch to force disabling of BLX instructions for
thumb interworking. This allows ld to emit code that is armv4t safe
even if configured for armv5 or later.
