Update to use CentOS Stream 9, intead of CentOS 7.6

Address issue with one table being unpinned, and another table not being
unpinned.

Fixed calls break exception handling, and largely aren't needed anymore.
We were still "fixing" calls when it had no fallthrough instruction,
assuming the call is used for something else.  Except that sometimes a
"call _cxa_throw" ends a function/section and legitimately has no
fallthrough.  And this breaks the exception handling.

Testing this fix against the Zipr test suite to verify that it is OK
on a large suite of programs.

Also added tests.

The main problem is the use of an addition instead of a multiplication for scale values.
In addition, to make sure the result can be used to create new instructions from assembly,
all generated numbers must be in hex.

Found bug resulting from hidden static variable in ctime() function.

Was previously asserting isRegister() or isMemory(), but could also be
isConstant().

* Update 68-sled code to be keystone friendly
* Corrected spelling of getInstruction.  removed extraneous assert.
* Disable should-pin-immediately because it interfers with sleds.
* Remove assert from fix-calls about odd prefixing, just dont fix the call.  More of an issue with FII doing disassembly
* Update switch->code discovery path to only happen if switch table is in text segment
* fixed FII to do what the last commit said -- only disassembly when TABLE is in text.  also patched zipr to handle xbegin gracefully.
* Disable verbose setting
* Create lots of dbs instead of just a few

Update find-in-function method to be more vague about the leas it finds when precise-switch-statement finding is impossible

Issue was related to intermediate set of the compare register.
Leveraged backup_until's stopif argument to stop backup until sooner.

Note: as indicated in code comment, single register/register move
is common and could be used to improve accuracy.

1) FII was finding the wrong cmp for switch tables.
Removed the blind cmp and forced the cmp to use the proper
register or not find a cmp.  Also changed the limit for a table
size when no cmp is found from 2^32 to 255.

2) Fixed an issue with zipr dollop layout where the size
to layout 1 instruction + a trampoline was bigger than laying
out two+ full dollops (because both dollops were short), but
the dollops are disallowed from being coalesced.  The worst-size
detector needed to account for non-coalescable dollops.

Debugging code allows for one to binary-search the unpins.

But a .dynsym, .got, etc. entry can be duplicated in it's own section
or other sections.  Unpinning has to handle unpinning an instruction
and deal with updating all tables properly.  Bug was found in handling
of the unpin for .dynsym in this regard.  This patch fixes that bug.
