X86RegisterInfo: eliminateFrameIndex: Avoid code duplication; NFC

Re-Commit of r300922 and r300923 with less aggressive assert (see
discussion at the end of https://reviews.llvm.org/D32205)

X86RegisterInfo::eliminateFrameIndex() and
X86FrameLowering::getFrameIndexReference() both had logic to compute the
base register. This consolidates the code.

Also use MachineInstr::isReturn instead of manually enumerating tail
call instructions (return instructions were not included in the previous
list because they never reference frame indexes).
