rs6000: build constant via li;rotldi
If a constant is possible to be rotated to/from a positive or negative
value which "li" can generated, then "li;rotldi" can be used to build
the constant.

* config/rs6000/rs6000.cc (can_be_built_by_li_and_rotldi): New function.
(rs6000_emit_set_long_const): Call can_be_built_by_li_and_rotldi.
gcc/testsuite/ChangeLog:
* gcc.target/powerpc/const-build.c: New test.
