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
alloca() used to allocate a few bytes extra most of the time so
most of the time the excess write did no harm.

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.

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.
