gas: bpf: new test for MOV with C-like numbers ll suffix
The BPF pseudo-c syntax supports both MOV and LDDW instructions:
mov: r1 = EXPR
lddw: r1 = EXPR ll
Note that the white space between EXPR and `ll' is necessary in order
to avoid ambiguity with the assembler's support for C-like numerical
suffixes. This patch adds a new test to the GAS BPF testsuite to make
sure that instructions like:
r1 = 666ll
are interpreted as `mov %r1,666', not as `lddw %r1,666'.
This matches clang's assembler behavior.

* testsuite/gas/bpf/alu-pseudoc.s: Add test to make sure C-like
suffix `ll' is not interpreted as lddw syntax.
* testsuite/gas/bpf/alu-pseudoc.d: Update expected results.
* testsuite/gas/bpf/alu-be-pseudoc.d: Likewise.
