from "llvm/Support/..." that are not llvm dependant.

Move files and fix #includes

69a86e4e23 The old getIndices has been deprecated, because it no longer works. It now
is named getIndicesBROKEN() and shall be removed when the codebase is updated
to not call it

6ad7c553fd Do the same for float->int that we did for int->float earlier.
Also check IsPointerType() in addition to IsIntegral() in several places.

ff5a09ee44 Fix bugs in FITOS/D instruction generation.
The space for optional args in the stack frame is now being computed,
so finish the code generation for the variable `alloca'.
Finally, made a major overhaul of how stack frame is managed.

b7f06f46a1 Fixed instruction information for RDCCR and WRCCR.
Fixed selection to create a TmpInstruction for each integer CC register
(since it is an implicit side-effect, unlike FP CC registers which are
explicit operands).

7fe27874be 1. Move most of the constant-fixup code into machine-independent file
InstrSelectionSupport.cpp.  It now happens in a bottom-up pass on
   each BURG tree after the original top-down selection pass on the tree.
2. Handle global values as constants (viz., constant addresses).

4cecdd206e Several fixes:
(1) Avoid hard-coding some register numbers.
(2) Fix some incorrect branch opcodes.
(3) Don't try to move int register to float register!
(4) If an operand being forwarded is a constant and it doesn't fit
    into the immed field of the copy machine instruction, then
    generate a load-constant instead of a copy.
(5) Use (unsigned long) 0 for copying a pointer via "add 0, ptr -> ptr2".
