bytecode_vm: fix memset on bigendian arch (bb #2478 ).
...
Otherwise memset's count is always 0, and we are using uninitialized bytes,
causing bytecode to misbehave.

bytecode_vm: fix apicall8
...
memstr() curiously always had haystack == needle for bytecode.
To fix this it helps if I actually read arg3 from ops[2] instead of ops[0]!

bytecode_vm: fix cli_bcapi_get_pe_section and cli_bcapi_disasm_x86.
...
They were not working on the interpreter, interpreter was seeing bounds errors
where there weren't any.
The 2nd parameter is a count, not a pointer size, the pointer's size
is a constant. Override the size for now.

bytecode_vm: restore stack_id after function return
...
This allows pointers to local stack variables to work correctly after a call.
Previously stackid was not restored, which caused bytecode_vm to stop bytecodes,
claiming it overrun the stack, when in fact it didn't.
(stackid stores stack size).

fix SIGBUS on Sparc.

Need to use the alignment of the largest possible type that we access, which is
uint64_t in this case.
void* can be 32-bits, and uint64_t still requires 64-bit alignment on Sparc,
when compiling for 32-bits (default).
