Denys Vlasenko 5154d4f2ad uprobes/x86: Fix 2-byte opcode table
Enabled probing of lar, lsl, popcnt, lddqu, prefetch insns.
They should be safe to probe, they throw no exceptions.

Enabled probing of 3-byte opcodes 0f 38-3f xx - these are
vector isns, so should be safe.

Enabled probing of many currently undefined 0f xx insns.
At the rate new vector instructions are getting added,
we don't want to constantly enable more bits.
We want to only occasionally *disable* ones which
for some reason can't be probed.
This includes 0f 24,26 opcodes, which are undefined
since Pentium. On 486, they were "mov to/from test register".

Explained more fully what 0f 78,79 opcodes are.

Explained what 0f ae opcode is. (It's unclear why we don't allow
probing it, but let's not change it for now).
