487aa0d537 sys: consolidate info about various targets 
Info about targets (like C arch/CFLAGS) is required in multiple places:
extract.sh
syz-extract
syz-sysgen
csource
vm/qemu
...

Consolidate it in one place and use that in syz-sysgen.

c0cabacda7 syz-fuzzer, syz-execprog: add -arch flag 
arch flag specifies target arch, which can be different from GOARCH.
For example, 386 executor with amd64 fuzzer.

f7b1163afb syz-manager/mgrconfig: explicitly specify target in config 
Add target config parameter (e.g. linux/amd64) which controls target OS/arch.
No more explicit assumptions about target.

3a866068b3 executor: fix 32-bit mode

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.

Update #191

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()
