9369cfea20 Fix the way parens are printed around "*ptrName" so that 
no parens are printed around  *, **, ... alone, except if
it is a pointer type for which no name should be printed,
as in the result of a cast.

3190395e10 Moved code here to extract memory instruction indices and to check 
whether FoldGetElemNodes should be called.  This is machine-independent
but was in the Sparc directory.  This is in a new function: GetMemInstArgs.

96a4efb0a6 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.

since uint is not normally sign-extended when casting to uint64_t.

1ae38466e6 - Fighting with linking problem due to removing the ::ID elements. Now the 
implementation .cpp files for analyses are not being included into gccas
    and friends because it is linking to the .a file and there is no explicit
    symbol reference to bring in the .o file.  The new IncludeFile hack is the
    result.
