- We can have the SyscallFunctionDefinitions be the correct size out of
the gate. Both tables are always 512 entries in size.
- In the RegisterSyscall_{32,64} handlers, just get the reference using
operator[]. We always know we will be under the size of the array, add
a an assert to check. Removes a bit of vector range checking overhead.
- Namespace 32-bit syscalls like 64-bit syscalls and include in the
regular header like 64-bit. This was just an oversight
- Use std::fill for the syscall gap for the invalid syscall, just a
minor cleanup.
No functional change.
