3a866068b3 executor: fix 32-bit mode 
The correct type is kernel long size, not user-space long size.
We approximate it with uint64.

ffe7e17368 prog, sys: move types to prog 
Large overhaul moves syscalls and arg types from sys to prog.
Sys package now depends on prog and contains only generated
descriptions of syscalls.
Introduce prog.Target type that encapsulates all targer properties,
like syscall list, ptr/page size, etc. Also moves OS-dependent pieces
like mmap call generation from prog to sys.

1c0d4caf7c sys: change BitfieldLast to BitfieldMiddle 
That's the condition we always want.
Currently we always check:
t.BitfieldOffset() == 0 || t.BitfieldLast()
now can check just:
!t.BitfieldMiddle()

08c91ab698 sys: support ptr64 type 
ptr64 is like ptr, but always takes 8 bytes of space.
Needed for some APIs. Unfortunately, most of these APIs
use buffer type, so we can't use ptr64 immidiately.

5a093b74f6 sys: change proc arguments to the format used by const/flags/len 
All other types have optional underlying type as the last argument.
Proc have it as first. This creates very irregular syntax and
complicates parsing. Make type the last argument.

Note: this is a breaking change if you have descriptions on the side.
