 - Returns addr of constant for argument + '\0'.
 - I couldn't think of a better name.
 - Move appropriate users of GetAddrOfConstantString to this.

Rename getStringForStringLiteral to GetStringForStringLiteral.

Add GetAddrOfConstantStringFromLiteral
 - This combines GetAddrOfConstantString and
   GetStringForStringLiteral. This method can be, but is not yet, more
   efficient.

Change GetAddrOfConstantString to not add terminating '\0'
 - <rdar://problem/6140956>

clarify the related comments. This fixes PR2670.

non-constant indices. Only a few of the peephole checks require
a constant index.

Make the allocation of LiveIntervals explicit, rather than holding them in the r2iMap_ by value.  This will prevent references to them from being invalidated
if the map is changed.

Updated checker state printer interface to allow transfer functions to return an arbitrary number of GRState::Printers.

track individual leaf values in such cases, so it needs to treat
struct values as normal values in this case.

ptrtoint can be turned into a bitcast if the
integer is at least as wide as a pointer.

The following case resulted in an invalid start location:

// start location not being set for ObjCProtocolDecl AST (when a forward reference is in scope).
@protocol Buggy;

has something to do with folding null values.

is lowered properly and covers everything LowerSELECT_CC did.
Added method printUnsignedImm in AsmPrinter to print uimm16 operands. This
avoid the ugly instruction by instruction checking in printOperand.
Added a swap instruction present in the allegrex core.
Added two conditional instructions present in the allegrex core : MOVZ and MOVN.
They both allow a more efficient SELECT operation for integers.
Also added SELECT patterns to optimize MOVZ and MOVN usage.
The brcond and setcc patterns were cleaned: redundant and suboptimal patterns
were
removed. The suboptimals were replaced by more efficient ones.
Fixed some instructions that were using immZExt16 instead of immSExt16.

    ObjCProtocolDecl directly.

Implement CodeGen support for forward protocol decls (no-ops are so
    nice to implement).

Also moved CGObjCRuntime.h out of CodeGenModule.h
