Fix Portable build

A previous change broke the ability to compile the Portable build.
Instead of building Portable, we unwittingly were building Iceland.
This CL fixes that, along with some bitrot unknowingly introduced
by subsequent CLs.

In particular, the debugger support change to add an intrinsic
call to associate value definitions with the original Dalvik
VReg broke llvm's Phi constraint.  Fixed.

However, problems remain.  Though the build is now fixed, CLs
subsequent to the makefile breakage broke the Portable llvm backend.
This CL will shift all Portable compilations to Iceland while the
new breakage is being addressed.
