Measure the specified inline asm to determine an approximation of its length.
Comments (which run till the next SeparatorString or newline) do not count as an instruction. Any other non-whitespace text is considered an instruction, with multiple instructions separated by SeparatorString or newlines. Variable-length instructions are not handled here; this function may be overloaded in the target code to do that. We implement the special case of the .space directive taking only an integer argument, which is the size in bytes. This is used for creating inline code spacing for testing purposes using inline assembly.

getRegisterInfo - TargetInstrInfo is a superset of MRegister info.
As such, whenever a client has an instance of instruction info, it should always be able to get register info as well (through this method).

isLoadFromStackSlot - If the specified machine instruction is a direct load from a stack slot, return the virtual or physical register number of the destination along with the FrameIndex of the loaded stack slot.
If not, return 0. This predicate must return 0 if the instruction has any side effects other than loading from the stack slot.
