MIPS: Create an artificial control register to hold the thread pointer.

In Linux, the set_thread_area system call stores the address of the thread
local storage area into a field of the current thread_info structure. Later,
to access that value, the program uses the rdhwr instruction to read a
"hardware register" with index 29. The 64 bit MIPS manual, volume II, says
that index 29 is reserved for a future ABI extension and should cause a
"Reserved Instruction Exception". In Linux (and potentially other ISAs) that
exception is trapped and emulated to return the value stored by
set_thread_area as if that were actually stored by a physical register.

The tp_value address (as named in the Linux kernel) is ironically stored as a
control register so that it goes with a particular ThreadContext. Syscall
emulation will use that to emulate storing to the OS's thread info structure,
and rdhwr will emulate faulting and returning that value from software by
returning the value itself, as if it was in hardware. In other words, we fake
faking the register in SE mode. In an FS mode implementation it should
work as specified in the manual.

Some of the micro-ops weren't casting 1 to ULL before shifting,
which can cause problems.  On the perl makerand input this
caused some values to be negative that shouldn't have been.

The casts are done as ULL(1) instead of 1ULL to match others

In one case, when moving a 32-bit value into an xmm register, the
lower half of the xmm register was not zero extended.
