Performance improvement on Cortex-A15 in both arm and thumb states on both
Dhrystone and Coremark, and improvement on Spec2000 in thumb state, with all
benchmarks showing improvements except three benchmarks in CFP2000 that have
slight regressions (189,183,178).

This patch updates ldm_stm_operation_p to check for loads that if SP is in
the register list, then the base register is SP. It guarantees that SP is
reset correctly when an LDM instruction is interrupted. Otherwise, we might
end up with a corrupt stack.

This sequence of patches adds support for epilogue generation in RTL.
This is the first part of Sameera's work on ARM prologue/epilogue. Sameera
Deshpande posted it for review in December 2011, having addressed all
previous comments: http://gcc.gnu.org/ml/gcc-patches/2011-12/msg00049.html.
The lat
ected number of vectorized loops is adjusted accordingly.
No regression with check-gcc on qemu for arm-none-eabi cortex-a9 neon softfp
arm/thumb.
OK for trunk?
Thanks,
Greta

There are a couple more test that need adjusting:

These tests fail on arm-none-eabi.
Below is a patch that fixes them.
