Replace {k,u}probe event argument fetching framework
with switch-case based. Currently that is implemented
with structures, macros and chain of function-pointers,
which is more complicated than necessary and may get
a performance penalty by retpoline.
This simplify that with an array of "fetch_ins
Unify {k,u}probe_fetch_type_table to probe_fetch_type_table
because the main difference of those type tables (fetcharg
methods) are gone. Now we can consolidate it.

Cleanup string fetching routine so that returns the consumed
bytes of dynamic area and store the string information as
data_loc format instead of data_rloc.
This simplifies the fetcharg loop.

Add "symbol" type to probeevent, which is an alias of u32 or u64

Add regs_get_argument() which returns N th argument of the

Add array type support for probe events.
This allows user to get arraied types from memory address.

x8/16/32/64, symbol, string) and N is a fixed value less

Whoops, I meant list_for_each_en
Add a testcase for $argN with kprobe event.
This tests whether the traced data is correct or not.
If the kernel doesn't support $argN (depends on arch),
it skips the test as UNSUPPORTED.

Since kprobes events support an array argument, perf-probe
can also support dumping array now.
The syntax are
[]
or

This can also be available with string type. In this
case, the string array should be "char *array[]" or
"char **array_ptr".
