perf annotate: Handle x86 instruction suffix generally

In AT&T asm syntax, most of x86 instructions can have size suffix like
b, w, l or q.  Instead of adding all these instructions in the table,
we can handle them in a general way.

For example, it can try to find an instruction as is.  If not found,
assuming it has a suffix and it'd try again without the suffix if it's
one of the allowed suffixes.  This way, we can reduce the instruction
table size for duplicated entries of the same instructions with a
different suffix.

If an instruction xyz and others like xyz<suffix> are completely
different ones, then they both need to be listed in the table so that
they can be found before the second attempt (without the suffix).
