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).

There are a couple more test that need adjusting:

FAIL: gcc.target
The compile error has nothing to do with the intended functionality of this
test. The error is due to the use of a bitfield in the test: enum rtx_code
code:16.
This patch adds the missing compiler option -fno-short-enums to the test.
