ICU-21363 Resurrect support for IBM's XL compiler

Browse source 
Yoshito is making this change on behalf of @datalogics-robb.
IBM's XL compiler can only support c++11 when the 'clang front end' is used.
This change modifies the configure step to use xlclang and  xlclang++
Change readme.html reference to xlC to refer to xlclang++ instead.
