[builtins] Avoid undefined behavior when calculating absolute value in floatsidf.c and floatsisf.c
When compiling compiler-rt with -fsanitize=undefined and running testcases you
end up with the following warning:
UBSan: floatsidf.c:32:9: negation of -2147483648 cannot be represented in type 'si_int' (aka 'long'); cast to an unsigned type to negate this value to itself
The same kind of pattern exists in floatsisf.c
This was found in an out of tree target.
