[patches] More PowerPC soft-float ULPs

["Joseph S. Myers" <joseph@xxxxxxxxxxxxxxxx>]

In PowerPC soft-float testing I found some more ULPs were needed.  (It's 
possible that these depend on fine details of the compiler and libc 
versions being tested; after all, no FSF GCC version has support for 
soft-float long double because the FSF GLIBC maintainers have no interest 
in reviewing the soft-fp patches needed for GCC.  The results of 
hard-float long double computations can definitely depend on what compiler 
optimizations happen in libgcc and libm.)

I'm not sure how the original ULP list was generated; it contains such 
oddities as

ildouble: 1
ldouble: 1
ildouble: 2
ldouble: 2

which suggest it was not generated by concatenating the old file with the 
new or increased ULPs and running through gen-libm-test.pl as described in 
README.libm-test (doing this yields other changes to the file as well, but 
it should be idempotent).
