Now, the implicit def comment will be emitted as a true PTX register name. Other targets can use this to customize the output of implicit def comments.

[NVPTX] Improve handling of FP fusion

We now consider the FPOpFusion flag when determining whether
to fuse ops.  We also explicitly emit add.rn when fusion is
disabled to prevent ptxas from fusing the operations on its
own.

Make AsmPrinter::emitImplicitDef a virtual method so targets can emit custom comments for implicit defs

For NVPTX, this fixes a crash where the emitImplicitDef implementation was expecting physical registers,
while NVPTX uses virtual registers (with a couple of exceptions).  Now, the implicit def comment will be
emitted as a true PTX register name. Other targets can use this to customize the output of implicit def
comments.

Fixes PR17519
