ab9f062166 GetArgument: Rework getArgument so that X86_FS compiles again.
When no size is specified for an argument, push the decision about what size
to use into the ISA by passing a size of -1.

518b5e5b1c Debug: Implement getArgument() and function skipping for ARM.
In the process make add skipFuction() to handle isa specific function skipping
instead of ifdefs and other ugliness. For almost all ABIs, 64 bit arguments can
only start in even registers.  Size is now passed to getArgument() so that 32
bit systems can make decisions about register selection for 64 bit arguments.
The number argument is now passed by reference because getArgument() will need
to change it based on the size of the argument and the current argument number.

For ARM, if the argument number is odd and a 64-bit register is requested the
number must first be incremented to because all 64 bit arguments are passed
in an even argument register. Then the number will be incremented again to
access both halves of the argument.

fae60c164e Arguments: Get rid of duplicate code for the Arguments class in each architecture.
Move the argument files to src/sim and add a utility.cc file with a function
getArguments() that returns the given argument in the architecture specific fashion.
getArguments() was getArg() is the architecture specific Argument class and has had
all magic numbers replaced with meaningful constants. Also add a function to the
Argument class for testing if an argument is NULL.
