radeon/llvm: Remove backend code from Mesa

This code now lives in an external tree.

For the next Mesa release fetch the code from the master branch
of this LLVM repo:
http://cgit.freedesktop.org/~tstellar/llvm/

For all subsequent Mesa releases, fetch the code from the official LLVM
project:
www.llvm.org

-// This pass performs the following transformation on instructions with
-// literal constants:
-//
-// %VGPR0 = V_MOV_IMM_I32 1
-//
-// becomes:
-//
-// BUNDLE
-//   * %VGPR = V_MOV_B32_32 SI_LITERAL_CONSTANT
-//   * SI_LOAD_LITERAL 1
-//
-// The resulting sequence matches exactly how the hardware handles immediate
-// operands, so this transformation greatly simplifies the code generator.
-//
-// Only the *_MOV_IMM_* support immediate operands at the moment, but when
-// support for immediate operands is added to other instructions, they
-// will be lowered here as well.
