(2) Use intelligent multiply selection code for array allocas.
(3) Don't use cache padding for alloca'd stack slots!
(4) Bug fix in handling call arguments: was not copying sixth FP arg
to int reg. when calling a function with no prototype.

Don't allow direct FP-to-uint conversion (must be eliminated by preselection).
Address arithmetic for arrays is now entirely 64-bit so no sign-ext needed.
llvm-svn: 3961
SetOperandsForMemInstr significantly). Load and Store
no longer have any indices. Eliminate spurious sign-extension
on a cast to float/double.

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.

-- 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

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.

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.

Improve checking for constants in Multiply.
Simpler method to keep track of when a node is folded into its parent.
Several other bug fixes.
llvm-svn: 1964
Also, use distinct names for the three types of SetMachineOperand to
avoid painful overloading problems and errors.
Bug fix in converting-int-to-float. Other minor stuff.
