x86/entry/64: Call all native slow-path syscalls with full pt-regs
This removes all of the remaining asm syscall stubs except for
stub_ptregs_64. Entries in the main syscall table are now all
callable from C.
The resulting asm is every bit as ridiculous as it looks. The
next few patches will clean it up. This patch is here to let
reviewers rest their brains and for bisection.
