Commit Message
Add sinhf function to bench-math and copy sinhf-inputs to benchtests.
Motivation for this patch is to prepare for upcoming libmvec new
functions. Float and double version of libmvec functions stays
together.
sinhf-inputs file generated from sinh-inputs file using following
scaling formula:
f = d * (FLT_MAX/DBL_MAX)
Where d is input(double) and f is output(float). If scaled float value
is duplicate in new input file, nextafterf() function used to find next
float value, ensuring no duplicates.

Dear Sunil,
the sinhf inputs contain many values such that sinhf(x) overflows, for
example the first one:
> +0x1.bcb612p+8
sage: x=RealField(24)("0x1.bcb612p+8",16)
sage: sinh(x)
6.83275e192
whereas the largest binary32 number is about 3.40282e38.
Paul
PS: despite my comments, I believe adding such inputs will be a nice addition.
