aebb01e004 GlobalISel: implement low-level type with just size & vector lanes. 
This should be all the low-level instruction selection needs to determine how
to implement an operation, with the remaining context taken from the opcode
(e.g. G_ADD vs G_FADD) or other flags not based on type (e.g. fast-math).

05e50bbdf6 GlobalISel: freeze reserved regs after IRTranslator. 
We can freeze the registers after the MachineFrameInfo has been configured (by
telling it about calls, inline asm, ...). This doesn't happen at all yet, but
will be part of IR translation.

Fixes -verify-machineinstrs assertion.

81284f84b6 [IRTranslator] Update getOrCreateVReg API to use references. 
A value that we want to keep in a virtual register cannot be null.

aa2c5cf11c [GlobalISel] Re-apply r260922-260923 with MSVC-friendly code. 
Original message:
Get rid of the ifdefs in TargetLowering.
Introduce a new API used only by GlobalISel: CallLowering.
This API will contain target hooks dedicated to call lowering.

8d3acd6266 [GlobalISel] Add the proper cmake plumbing. 
This patch adds the necessary plumbing to cmake to build the sources related to
GlobalISel.

To build the sources related to GlobalISel, we need to add -DBUILD_GLOBAL_ISEL=ON.
By default, this is OFF, thus GlobalISel sources will not impact people that do
not explicitly opt-in.
