The jump table symbol is accessed only from the function symbol
(in the same package), so it can be static. Also, if the function
is DUPOK and it is, somehow, compiled differently in two different
packages, the linker must choose the jump table symbol associated
to the function symbol it chose. Currently the jump table symbol
is DUPOK, so that is not guaranteed. Making it static will
guarantee that, as each copy of the function symbol refers to its
own jump table symbol.

The syscall_SyscallX functions currently discard the nargs parameter
when calling syscall_SyscallN. This precludes some optimizations
down the line. For example, on amd64, a syscall that takes 0 arguments
don't need to set any of the params passing registers (CX, DX, R8, and
R9).
This CL updates all syscall_SyscallX functions so they call
syscall_SyscallN with an argument slice of the right length.
While here, remove the hack in syscall_SyscallN to support less than 4
arguments, and update instead asmstdcall on amd64 to properly handle
this case.

When transitioning between the old object loader and the new
object loader, to support both we made loadelf to take symbol
loading functions as function pointers. Now we only have the new
object loader. Change the function pointers back to static calls.

Sometimes we found that benchmark results may strongly depend on
the ordering of functions laid out in the binary. This CL adds a
flag -randlayout=seed, which randomizes the function layout (in a
deterministic way), so can verify the benchmark results against
different function ordering.

Enable canRotate for riscv64, enable rotation intrinsics and provide
better rewrite implementations for rotations. By avoiding Lsh*x64
and Rsh*Ux64 we can produce better code, especially for 32 and 64
bit rotations. By enabling canRotate we also benefit from the generic
rotation rewrite rules.

The call site calculation in the previous version is incorrect. For
the PGO preprocess file, the compiler should directly use the call
site offset value. Additionly, this change refactors the preprocess
tool to clean up unused fields including startline, the flat and the
cum.
