fa0cf8dc2e Recommited r156374 with critical fixes in BitcodeReader/Writer: 
Ordinary patch for PR1255.
Added new case-ranges orientated methods for adding/removing cases in SwitchInst. After this patch cases will internally representated as ConstantArray-s instead of ConstantInt, externally cases wrapped within the ConstantRangesSet object.
Old methods of SwitchInst are also works well, but marked as deprecated. So on this stage we have no side effects except that I added support for case ranges in BitcodeReader/Writer, of course test for Bitcode is also added. Old "switch" format is also supported.

35fe399b7f Delete all functions that are no longer needed in MipsFunctionInfo, including 
the ones that get or set the frame index for the $gp save slot. 

Remove the piece of code in MipsFunctionInfo::getGlobalBaseReg() which returns
GP. This function should always return a virtual register.

ae43b7da61 Make the following changes in MipsISelLowering.cpp: 
- Stop creating stack frame objects needed for saving $gp.
- Insert a node that copies the global pointer register to register $gp
  before the call node. This will ensure $gp is valid at the entry of the
  called function.

afe973fad4 Speed up computeComposites() by using the new SubReg -> SubIdx map. 
TableGen doesn't need to search through the SubRegs map to find an
inverse entry.

431ee824c6 Make the following changes in MipsAsmPrinter.cpp: 
- Remove code which lowers pseudo SETGP01.
- Fix LowerSETGP01. The first two of the three instructions that are emitted to
  initialize the global pointer register now use register $2.
- Stop emitting .cpload directive.

aff911c34c Don't look for empty live ranges in the unions. 
Empty live ranges represent undef and still get allocated, but they
won't appear in LiveIntervalUnions.

bc52a1662b Insert instructions to the entry basic block which initializes the global 
pointer register. 


This is the first of the series of patches which clean up the way global pointer
register is used. The patches will make the following improvements:

- Make $gp an allocatable temporary register rather than reserving it.
- Use a virtual register as the global pointer register and let the register
  allocator decide which register to assign to it or whether spill/reloads are
  needed.
- Make sure $gp is valid at the entry of a called function, which is necessary
  for functions using lazy binding.
- Remove the need for emitting .cprestore and .cpload directives.
