15a0456d0b Remove unnecessary instructions from x86/x86_64 syscalls. 
__set_errno returns -1 exactly so that callers don't need to bother.
The other architectures were already taking advantage of this, but
no one had ever fixed x86 and x86_64.

15b91e92a0 Fix x86 cfi directives for syscalls. 
The syscall generation always used 4 bytes for each push cfi directive.
However, the first push should always use an offset of 8 bytes, each
subsequent push after that is only 4 bytes though.
