Initialize LiveOutInfo's APInt members to zero, as APInt's

default constructor produces an uninitialized APInt.
This fixes PR3896.

Add sub/mul overflow intrinsics. This currently doesn't have a

target-independent way of determining overflow on multiplication. It's very
tricky. Patch by Zoltan Varga!

Implement "visitPow". This is mainly used to see if we have a pow() call of this
...
form:
powf(10.0f, x);
If this is the case, and also we want limited precision floating-point
calculations, then lower to do the limited-precision stuff.

Add -flimit-float-precision to enable some faster,

but less accurate (non-IEEE) code sequences for
certain math library functions. Add the first of
several such expansions. Don't worry, if you don't
turn it on it won't affect you.
