8 hoursadd behavior information for x86_64 instructionsiximeow
this is a squash of a few months' hacking, including but not limited to what eventually got extracted into https://git.iximeow.net/asmlinator/about/ the path here is generally not historically interesting, and the vast majority of this diff is very particular static data tables (BehaviorDigests and implicit operand lists) `src/long_mode/behavior.rs` will more or less be directly adapted into versions for x86-32 and x86-16, similar to the instruction decoders.

these instructions, it turns out, have fixed operand size based on CPU execution mode and regardless of prefixes. good to know!

2023-12-16abnormal memory sizes for keylocker instructions are not bugsiximeow
new `does_not_decode_invalid_registers` fuzzer found other bugs! the 384-bit accesses for 128b keylocker instructions are an otherwise-unknown size and had a memory size of `BUG`. they are not bugs. give the memory size a real name.

2023-07-04fix some dancing between bank size and RegisterBank enum valuesiximeow
in the process, fixed a decoding bug dealing with a0/a1/a2/a3 movs (respected rex.b when rex.b should have been ignored) this seems to maybe improve runtime ever so slightly, but this is really meant as a cleanup commit more than anything.
2023-03-05add `Opcode::is_jcc`, `Opcode::is_setcc`, and `Opcode::is_cmovcc` helpersiximeow
this request/suggestion comes from [github](https://github.com/iximeow/yaxpeax-x86/issues/29)! thank you!
2023-02-19deprecate `pub fn cs`, which is an intensely embarrassing bug of a functioniximeow
unlike every other function to test if a particular selector is picked by prefixes, `Prefixes::cs` does not return bool, nor does it check the currently-selected prefix. instead, it modifies the decoded `Prefixes` to set the current prefix to `cs`. this has been a bug all the way since 0.0.1 was released. the function now does nothing, and is marked deprecated. in a future 2.x release, the function will be changed to return `bool` and be in-line with other segment selector-checking functions. in the mean time, a new `Prefixes::selects_cs()` does the correct thing. thank you to @meithecatte who pointed this out in https://github.com/iximeow/yaxpeax-x86/issues/28!

2022-04-24fix a few issues preventing no-std builds from ... buildingiximeow
this includes a `Makefile` that exercises the various crate configs. most annoyingly, several doc comments needed to grow `#[cfg(feature="fmt")]` blocks so docs continue to build with that feature enabled or disabled. carved out a way to run exhaustive tests; they should be written as `#[ignore]`, and then the makefile will run even ignored tests on the expectation that this will run the exhaustive (but slower) suite. exhaustive tests are not yet written. they'll probably involve spanning 4 byte sequences from 0 to 2^32-1.
