gas: BPF pseudo-c syntax tests

This patch expands the GAS BPF testsuite in order to also test the
alternative pseudo-C syntax used in BPF assembly.

This includes three main changes:

- Some general GAS tests involving assignment and equality operands in
  expressions (such as = and ==) are disabled in bpf-* targets,
  because the syntax collides with the pseudo-C BPF assembly syntax.

- New tests are added to the BPF GAS testsuite that test the pseudo-c
syntax.  Tests for all BPF instructions are included.

- New tests are added to the BPF GAS testsuite that test the support
  for both syntaxes in the same source.
