JIT: more optimizing of float ops based on known input characteristics
...
If the inputs are both float singles, and the top half is known to be identical
to the bottom half, we can use packed arithmetic instead of scalar to skip
the movddup.
This is slower on a few rather old CPUs, plus the Atom+Silvermont, so detect
Atom and disable it in that case.
Also avoid PPC_FP on stores if we know that the output came from a float op.

Fix the brand/cpu_string reversal.
...
Before this commit, the two were reversed ("cpu_string" had the brand, e.g. "AuthenticAMD"; and "brand_string" had the CPU type, e.g. "AMD Phenom II X4 925").

Don't set DAZ on x86 in non-IEEE mode.

I have no idea why we were using it in the first place; it doesn't match
the behavior of PPC NI flag.
