0e610290d0 config: remove ruby's requirement on the timing cmd line param 
Since ruby only works in timing mode, explicitly requiring the timing cmd line
param to be specified is not necessary.

7a6ed1b10b Power: Get rid of unused checkFpEnableFault. 
This function was brought in from another ISA and doesn't actually do anything
or get used.

9581562e65 X86: Get rid of the flagless microop constructor.

f6182f948b X86: Make the TLB fault instead of panic when something is unmapped in SE mode. 
The fault object, if invoked, would then panic. This is a bit less direct, but
it means speculative execution won't panic the simulator.

69fc2af006 X86: Add a .serializing directive that makes a macroop serializing. 
This directive really just tells the macroop to set IsSerializing and
IsSerializeAfter on its final microop.

5a1dbe4d99 X86: Consolidate extra microop flags into one parameter. 
This single parameter replaces the collection of bools that set up various
flavors of microops. A flag parameter also allows other flags to be set like
the serialize before/after flags, etc., without having to change the
constructor.

43c938d23e O3: Handle loads when the destination is the PC. 
For loads that PC is the destination, check if the load
was mispredicted again when the value being loaded returns from memory

5f91ec3f46 ARM/O3: store the result of the predicate evaluation in DynInst or Threadstate. 
THis allows the CPU to handle predicated-false instructions accordingly.
This particular patch makes loads that are predicated-false to be sent
straight to the commit stage directly, not waiting for return of the data
that was never requested since it was predicated-false.
