8e4ec55703 Changed the floating point register file into a class with appropriate accessor functions. The width of the floating point register to access can be specified, and if not, it will be accessed at its "natural" width. That is, the width of each individual register. Also, the functions which access the bit representation of floating point registers can use the blahblahBits functions now instead of blahblahInt.
arch/alpha/arguments.cc:
    Renamed readFloatRegInt to readFloatRegBits
arch/alpha/ev5.cc:
    Removed the Double from setFloatRegDouble
arch/alpha/registerfile.hh:
    Changed the floating point register file from a union of arrays to a class with appropriate accessor functions. The interface is necessary for SPARC.
arch/alpha/types.hh:
    Changed the FloatReg type from a union of uint64_t and double to a double, and defined a new type FloatRegBits which is a uint64_t and is used to return the bits which compose a floating point register rather than the value of the register.
arch/isa_parser.py:
    Adjusted the makeRead and makeWrite functions to generate the new versions of readFloatReg and setFloatReg.
base/remote_gdb.cc:
kern/tru64/tru64.hh:
    Replaced setFloatRegInt with setFloatRegBits
cpu/cpu_exec_context.cc:
    Removed the duplicated code for setting the floating point registers, and renamed the function to setFloatRegBits and readFloatRegBits.

f045b110cf Have a copyRegs function defined in the ISA that copies registers from one ExecContext to another ExecContext. This makes it easier for anything that needs to copy architected registers to do so in an ISA independent fashion.
arch/alpha/ev5.cc:
    copyIprs now copies from a source ExecContext to a destination ExecContext.
arch/alpha/registerfile.hh:
    Have ISA specific functions to copy all architected registers from one ExecContext to another.
cpu/cpu_exec_context.cc:
    Call the ISA in order to copy any architected registers.

38dd86ce72 Fix TranslatingPort access functions to:
- know nothing about Fault objects (as it should be)
- call fatal() by default on accesses to unmapped addrs
- provide "try" versions for callers that are prepared to handle failure

mem/translating_port.cc:
mem/translating_port.hh:
    Memory system objects should not return Fault objects, just errors.
    Half the time we don't check the return code anyway, so make
    default version of the access functions call fatal().
    Provide "try*" versions that return a bool for places where we
    really are going to check the return code.
sim/syscall_emul.cc:
sim/syscall_emul.hh:
    Need to use new "tryReadString" here since we actually check the return code.

1141610a01 Bump up NFS wait time in qdo (since this has been causing
problems in pool regressions).

util/qdo:
    Bump up hardcoded NFS wait time from 45 sec to 90 sec (and
    print threshold from 10 sec to 30 sec).  Would be even
    nicer to make these cmd-line params, but nobody would use
    them anyway.
