Test cases added as @eli.friedman kindly advised.
I am wondering do we really need them and need them in asm clobber form.
The questions originated from initial commit  be881e283173 <https://reviews.llvm.org/rGbe881e2831735d6879ee43710f5a4d1c8d50c615> with pre-commit code review D78252 <https://reviews.llvm.org/D78252> approved.
Then thanks to @ab notes I committed fixes to first parts of patterns(V16-V31 registers restrictions), although 
all used v*i16_indexed patterns in second part had already V16-V31 restrictions in place and no issues were found. 
Restrictions are tested by llvm/test/MC/AArch64/fullfp16-diagnostics.s
So test cases under review just additionally check that V16-V31 are not allocated in f16 indexed patterns.
