29127b8825 Change interface of MachineOperand as follows:
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse()
    b) add isUse(), isDef()
    c) rename opHiBits32() to isHiBits32(),
              opLoBits32() to isLoBits32(),
              opHiBits64() to isHiBits64(),
              opLoBits64() to isLoBits64().

This results to much more readable code, for example compare
"op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used
very often in the code.

5ca15c8f5e Add a floating point killer pass. This pass runs before register
allocaton on the X86 to add information to the machine code denoting
that our floating point stackifier cannot handle virtual point
register that are alive across basic blocks. This pass adds an
implicit def of all virtual floating point register at the end of each
basic block.

93c209e4ac Modified cast so that it converts the int to a long before casting to
a pointer.  This evades a warning emitted by GCC when we cast from
unsigned int (32 bit) to void * (64 bit) on SparcV9.

fb0c4c3d39 Since we are using a gep_type_iterator, we apparently must get the type

e962a55ac5 In getObjectType(), doxygenify comment, and take a pointer to the
beginning of the archive member data as an argument.

Get rid of ParseLongFilenameSection(), which is dead.

In ReadArchiveBuffer(), implement support for 4.4BSD/MacOSX long filenames.
This is kind of invasive, because they prepend the long filename to the archive
member data, and then lie about the size. So we have to keep track of the real
size.

e7599245cb Add support for --debug-only=interpreter, to print out instrs before
interpreting them.

Move support for getting the value of a ConstantExpr into
getConstantExprValue(), and add support for the rest of the different
kinds of ConstantExprs.  (I don't think I like ConstantExprs!)
This requires separate procedures executeShlInst() and executeShrInst().

Reduce the number of references to TheEE.

Get rid of an old comment mentioning annotations.

Fix exitCalled(), which was crashing the Interpreter. This was a
leftover from the return-value code refactoring.

c299416f67 Fixed the CBE on Solaris/Sparc. We need to define the return value of
the write() system call because it returns 64 bits on Solaris 64 bit,
and an implicit return value of int says it returns 32 bits.
Admittedly, this is a bit of a hack.
