ba5c703619 Do not hastily change the Opcode from 'r' to 'i' type if we're not actually
SETTING the operand to be an immediate or have verified that one of the operands
is really a SignExtended or Unextended immediate value already, which warrants
an 'i' opcode.

b126ea43eb I have finally seen the light. The code to change the opcode must live higher in
the loop, and in both cases. In the first case, it is a VReg that is a constant
so it may be actually converted to a constant. In the second case, it is already
a constant, but then if it doesn't change its type (e.g. to become a register
and have the value loaded from memory if it is too large to live in its
instruction field), we must change the opcode BEFORE the 'continue', otherwise
we miss the opportunity.

d43c10b583 Added MachineCodeForInstruction object as an argument to
TmpInstruction constructors because every TmpInstruction object has
to be registered with a MachineCodeForInstruction to prevent leaks.
This simplifies the user's code.

3a54b695ce Significant improvement: GEP used by a load or store no longer generates
a separate ADD; instead just use the indexed load/store instruction!
Also, a bug fix: folding a GEP with a leading non-zero index with
its predecessor was incorrect: now it only happens if the predecessor
is pointing to an indexable type (aka SequentialType).

whether FoldGetElemNodes should be called.  This is machine-independent
but was in the Sparc directory.  This is in a new function: GetMemInstArgs.

3489677a7e Add function GetConstantValueAsUnsignedInt.
Fix 2 bugs in FoldGetElemChain so index vector is not modified
when no GEPs are folded in, and so a hasLeadingZero is computed
only for the last folded GEP, not the one after that if any.
