Summary: The default opt-level was recently lowered from 1 to 0. `syscalls::syscall!(...)` has one branch to check the error code while `syscalls::raw_syscall!()` does not. Presumably, this branch was getting optimized out when opt-level=1, but not when opt-level=0 and thus started causing the highly-sensitive timer tests to start failing.

Summary: We want to allow precise timers with an instruction offset. While single stepping we have target and current value of the counter and once we match branches we only increment instructions

Summary: Now that `Tool` doesn't require `Serialize` and `Deserialize`, we can remove these unnecessary derives. Hopefully this will have a slight improvement to compile-times.

Summary: If an RPC fails to send, there isn't much that can be done to handle it. In all call sites so far, they all just unwrap the error because it can't be handled properly. If an RPC fails, it is a programmer error (because the request/response failed to serialize/deserialize) and indicates a bug in our code.

Summary:
See https://github.com/jasonwhite/syscalls/blob/master/CHANGELOG.md
The biggest change here is that the type of syscall registers and return values was changed from `u64` to `usize` (to support 32-bit architectures).

Summary:
The `llvm_asm` nightly feature was removed in Rust 1.59 and `asm!()` was simultaneously stabilized, so we need to make the switch so things continue compiling.
This retains the `llvm_asm` code so that it can continue compiling on old llvm versions. This will be removed when that is updated.
