bpf: there is no ldinddw nor ldabsdw instructions
There are no legacy ldind nor ldabs BPF instructions with BPF_SIZE_DW.
For some reason we were (incorrectly) supporting these. This patch
updates the opcodes so the instructions get removed and modifies the
GAS manual and testsuite accordingly.
See discussion at
https://lore.kernel.org/bpf/110aad7a-f8a3-46ed-9fda-2f8ee54dcb89@linux.dev
Tested in bpf-uknonwn-none target, x86-64-linux-gnu host.
