Made LEA memory operands emit only 4 MCInst operands.
Made the scale operand equal 1 for instructions that have no
SIB byte.

load is needed when we have a small store into a large alloca (at which 
point we get a load/insert/store sequence), but when you do a full-sized
store, this load ends up being dead.

This dead load is bad in really large nasty testcases where the load ends
up causing mem2reg to insert large chains of dependent phi nodes which only
ADCE can delete.  Instead of doing this, just don't insert the dead load.

This fixes rdar://6864035

so, take the major array bound as the size to allocate. Fixes PR5833.

Switch InitializedEntity from TypeLoc down to just QualTypes, since we don't use the location information but we did spend a bunch of time building faked-up TypeLocs

While converting one of the operands to a memory operand, we need to check if it is Legal and does not result into a cyclic dep.

InitializationSequence (when a FunctionDecl is present). This required
a few small fixes to initialization sequences:

  - Make sure to use the adjusted parameter type for initialization of
  function parameters.
  - Implement transparent union calling semantics in C

Make sure that we mangle overloaded operators that are member functions correctly, giving them the correct arity.

With this seemingly insignificant fix, we are now able to build and link clang using clang itself! (LLVM still has to be built with gcc for the time being).
