RegsForValue - This struct represents the registers (physical or virtual) that a particular set of values is assigned, and the type information about the value.
The most common situation is to represent one value at a time, but struct or array values are handled element-wise as multiple values. The splitting of aggregates is performed recursively, so that we never have aggregate-typed registers. The values at this point do not necessarily have legal types, so each value may require one or more registers of some legal type.

AddInlineAsmOperands - Add this value to the specified inlineasm node operand list.
This adds the code marker, matching input operand index (if applicable), and includes the number of values added into it.

Regs - This list holds the registers assigned to the values.
Each legal or promoted value requires one register, and each expanded value requires multiple registers.

RegVTs - The value types of the registers.
This is the same size as ValueVTs and it records, for each value, what the type of the assigned register or registers are. (Individual values are never synthesized from more than one type of register.)
With virtual registers, the contents of RegVTs is redundant with TLI's getRegisterType member function, however when with physical registers it is necessary to have a separate record of the types.
