Add exp10 macro to <tgmath.h> (bug 26108)
glibc has had exp10 functions since long before they were standardized; now they are standardized in TS 18661-4 and C2X, they are also specified there to have a corresponding type-generic macro. Add one to <tgmath.h>, so fixing bug 26108. glibc doesn't have other functions from TS 18661-4 yet, but when added, it will be natural to add the type-generic macro for each function family at the same time as the functions. Tested for x86_64.
