Modified Files:
        basesrc/lib/libpthread/arch/i386 [nathanw_sa]: pthread_switch.S

Log Message:
Actually, we *do* need pthread__switch in assembler, in order that
the ucontext_t be the last thing on the stack. Otherwise, the switch
code will overwrite stack data, since it sets the stack to pt_uc.

Use the UT_EIP symbolic constant.

When performing a new_preempt, store into pt_switchto and
pt_switchtouc of the *new* thread, so that resolve_locks stands a
chance of finding the switchto victim.
