bitkeeper revision 1.1236.25.21 (4235d857_qyCkzeGWIe4csiWvPwPYQ)

Reduce reliance on complicated pre-exception system in 32-bit and
64-bit entry.S files. Various x86/64 cleanups, and we now flag to the
kernel whether it is interrupting a kernel or user context using saved
RFLAGS[63:56] (equivalently, the byte at RFLAGS+7(%rsp)). Non-zero byte
indicates kernel context.
