aarch64: Fix FEAT_B16B16 sve2 instruction constraints.
This patch adds missing contraints to FEAT_B16B16 sve2 instructions
bfclamp, bfmla and bfmls and add negative tests for all the bfloat
instructions.
The bfloat16-invalid.* testcases are renamed to bfloat16-1-invalid.*
to maintain consistency in the testsuite.
The bfloat16-1-invalid.* tests are modified so that "selected
processor does not support" is generated by the assembler, since
+b16b16 is not passed in the command line.
The bfloat16-2-invalid.* testcase includes the wrong operands
bfloat16 tests.
