When zero extending a 32-bit register, we emit a "mov", but currently
report the cost of the "mov" incorrectly.
In terms of speed, we currently say the cost is that of an extend
operation. But the cost of a "mov" is the cost of 1 instruction, so fix
that.
In terms of size, we currently say that the "mov" takes 0 instructions.
Fix it by changing it to 1.
Bootstrapped and tested on aarch64-none-elf.

* config/aarch64/aarch64.c (aarch64_rtx_costs): Fix cost of zero extend.

C++11 has a
static_assert (COND, MESSAGE)
which gives more readable error messages for STATIC_ASSERT than our
current implementation.
This patch makes us use it if __cplusplus >= 201103L
There's also a provisional static_assert (COND) in C++1z, but presumably
we should wait until that one is fully standardized before using it.
