reg_alloc: Fix for LLVM's interpretation of the System V ABI
...
This aspect of the System V ABI is under-defined. LLVM choses a
different interpretation from GCC and ICC.
Most other compilers assume the callee is responsible zero-ing the
upper bits of the register if necessary. LLVM assumes the caller
has zero-extended the register.
This is a quick fix for this problem until zext-tracking is
implemented.

reg_alloc: Register allocator related constraints belong with the rest of the register allocator
...
HostLocToReg64 contained two DEBUG_ASSERTs invloving constraints that
really belonged to the register allocator.
The register allocator prevents allocation of RSP and R15 because those
are reserved for the stack pointer and the state pointer respectively.

reg_alloc: Make GetRegLoc return by const reference
...
Considering a HostLocInfo instance houses a std::vector, every time this
function is called can cause a potential heap allocation.
This can be somewhat unnecessary because this function is only used to query
for information we already have.
Considering this is used by several other internal query functions such as
IsRegisterOccupied, IsRegisterAllocated, and IsLastUse, this will result
in better codegen (returning an address is just 3 instructions excluding
the ret instruction for returning, meanwhile heap alloc can be 60+).
This also renames the function to have the same name as its non-const
counterpart, since overloading will just select the correct function
instead of putting that onus on the developer.
