Incorporate MSVC's __declspec(noalias) #54
Description
Microsoft's __declspec(noalias) is documented as:
noalias means that a function call doesn't modify or reference visible global state and only modifies the memory pointed to directly by pointer parameters (first-level indirections).
So it is analogous to gcc/clang __attribute__((const)). Currently HEDLEY_CONST does not generate it.

According to the gcc docs.
const functions should never take pointer or, in C++, reference arguments.This seems to conflict with msdn noalias docs
noalias means that a function call doesn't modify or reference visible global state and only modifies the memory pointed to directly by pointer parameters (first-level indirections).These appear to be incompatible, im not sure
HEDLEY_CONSTwould be a correct place for__declspec(noalias)
