[BPF] Mark pseudo insn patterns as isCodeGenOnly
These pseudos are not supposed to be visible to user.
This patch reduced the auto-generated instruction matcher. For example,
the following words are removed from keyword list of LLVM BPF assembler.
- MCK__35_, // '#'
- MCK__COLON_, // ':'
- MCK__63_, // '?'
- MCK_ADJCALLSTACKDOWN, // 'ADJCALLSTACKDOWN'
- MCK_ADJCALLSTACKUP, // 'ADJCALLSTACKUP'
- MCK_PSEUDO, // 'PSEUDO'
- MCK_Select, // 'Select'
