Kernel: Include the current instruction pointer in profile samples
...
We were missing the innermost instruction pointer when sampling.
This makes the instruction-level profile info a lot cooler! :^)

AK: Add global FlatPtr typedef. It's u32 or u64, based on sizeof(void*)
...
Use this instead of uintptr_t throughout the codebase. This makes it
possible to pass a FlatPtr to something that has u32 and u64 overloads.

Kernel+ProfileViewer: Move symbolication to userspace for time profiles
...
This makes the time profiles look like the memory profiles so we can
use the userspace symbolication code in ProfileViewer.

Kernel: Replace "current" with Thread::current and Process::current
...
Suggested by Sergey. The currently running Thread and Process are now
Thread::current and Process::current respectively. :^)

Kernel: Start working on a syscall for logging performance events
...
This patch introduces sys$perf_event() with two event types:
- PERF_EVENT_MALLOC
- PERF_EVENT_FREE
After the first call to sys$perf_event(), a process will begin keeping
these events in a buffer. When the process dies, that buffer will be
written out to "perfcore" in the current directory unless that filename
is already taken.
This is probably not the best way to do this, but it's a start and will
make it possible to start doing memory allocation profiling. :^)
