4053862c26 prog: fix determinism in choice table 
Floats bite.
We interated over uses map non-deterministically,
which would be fine overall except that it may
break floats due to rounding.

d06aafeef6 prog: fix determinism in resource creation 
We chosen a non-deterministic resource in createResource
due to map iteration order.
This is caught by existing TestDeterminism,
but just very infrequently.

vm/isolated: fix hang when target_reboot is not set 
* updated the contributor list

* Fixes #1750, syz-manager hangs with "target_reboot:" false in isolated VM mode

If in the isolated VM mode, "target_reboot": false option is set in the
syz-manager's configuration, it hangs forever. syz-manager essentially
keeps on waiting for the VM to reboot, while a reboot is never triggered
due to target_reboot option being set to false. The fix is to perform the
waitRebootAndSSH() check only when target_reboot is set to true.

File(s) changed:

    vm/isolated/isolated.go: Move the waitRebootAndSSH() check inside the correct block

d7f9fffab3 targets: syz-extract: add Clang support for Linux builds 
Allow targets.go use Clang instead of the default Linux compiler by
setting the SYZ_CLANG=1 env var. Doing so changes the compiler to
"clang" and the linker to "ld.ldd", assuming they are in $PATH, and adds
the --target and -ferror-limit CFLAGS.

Target also exports KernelCompiler and KernelLinker fields now, which allows
overriding the compiler and linker in the kernel make invocation.
