The attached patch fixes an out of bound write to memory allocated
with alloca() on the stack.  This rarely ever happened because on
one hand -fbounds-check needs to be enabled, and on the other hand

From-SVN: r238822

On AArch64 the UXTB and UXTH instructions are aliases of UBFM,

which does a shift as part of its operation. An AND immediate is a
simpler operation, and might be faster on some implementations, so
it is better to emit this this instead of UBFM.

Benchmarking showed no difference on implementations where UBFM has
the same performance as AND, and minor speedups across several
benchmarks on an implementation where UBFM is slower than AND.

This patchset improves zero extend costs and code generation.

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.
