0374b8de2b - Change getelementptr instruction to use long indexes instead of uint 
indexes for sequential types.

ec7f482d90 Silly bug fix: Machine code vector could be empty for a no-op cast instruction, 
e.g., cast double to double.

babc0fab19 -- Use size of pointer element type instead of pointer type in array offsets! 
-- A few bug fixes in casting between floats and ints.
-- Use SRL reg, 0 instead of AND reg, 0xffffffff to clear high 32 bits.

0c4e886dbf - Renamed Type::isIntegral() to Type::isInteger() 
- Added new method Type::isIntegral() that is the same as isInteger, but
    also accepts bool.

8cfffd3a3e Sign-extend values used to index arrays (and Simplify 
SetOperandsForMemInstr significantly).  Load and Store
no longer have any indices.  Eliminate spurious sign-extension
on a cast to float/double.

6418eac2f1 Have to save a boolean (setCC) value whenever use is outside the current 
basic block.

Mark setCCInstr used as dest. of conditional-move as both a def and a use.

BA instruction no longer has the unused CC argument.

242a8086aa Numerous bug fixes: 
-- correct sign extensions for integer casts and for shift-by-constant
   instructions generated for integer multiply
-- passing FP arguments to functions with more than 6 arguments
-- passing FP arguments to varargs functions
-- passing FP arguments to functions with no prototypes
-- incorrect stack frame size when padding a section
-- folding getelementptr operations with mixed array and struct indexes
-- use uint64_t instead of uint for constant offsets in mem operands
-- incorrect coloring for CC registers (both int and FP): interferences
   were being completely ignored for int CC and were considered but no
   spills were marked for fp CC!

Also some code improvements:
-- better interface to generating machine instr for common cases
   (many places still need to be updated to use this interface)
-- annotations on MachineInstr to communicate information from
   one codegen phase to another (now used to pass information about
   CALL/JMPLCALL operands from selection to register allocation)
-- all sizes and offests in class TargetData are uint64_t instead of uint

dbc4fad577 Insert copy operations for FP arguments to a varargs function, 
to copy the FP arg. to an integer.  Necessary so that the
register allocator has two different live ranges for the FP value
and the int. argument.

6111a87b3a Move the InsertPrologEpilogCode class out of the Sparc.cpp file into the 
new PrologEpilogCodeInserter.cpp file, and include the bodies of the
GetInstructionsFor(Prolog|Epilog) functions from SparcInstrSelection.cpp
into the class.  This eliminates the need for a static global vector of
instructions and a class of errors that is really unneccesary.
