Update to fix calls for exception handling.

See merge request !27

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.

Remove ubuntu16 CI, change docker/deployment to ubuntu 22.

Resolve "Generated binary crashes for varargs compiled with icc"

Closes #18

See merge request !24

Fix naming

See merge request !23

Resolve "Rida crashes if .plt section is empty"

Closes #15

See merge request !20

Also added tests.

Fix some minor bugs

See merge request !21

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.

Temp fix: to deal with FII creating overlapping switch table scoops
resulting from imprecision in ICX-created programs.

Todo:  Update FII to not create overlapping scoops.

Only gap-fill for original-style scoops (that is, pure-data).  R/X
scoops are added for switch tables, but may overlap because the
switch detector may make multiple guesses at ground truth.  The gap
filling algorithm wasn't expecting this, so skip these scoops as
they shouldn't result in gap-filling anyhow.

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

Improve symbol parsing speed for rida.

Update free-range management to keep free ranges sorted by size and address.

See merge request !17

This was needed because sorting by address ended up being _very_ slow to
find free spaces in large programs.  E.g., if 100,000 1-byte free
ranges were created (and, likely unusable), placing every instruction
after this point will need to search thouse 100,000 free ranges.

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

Work through issues discovered in GT benchmark suite.

* 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.
