This is an attempt at rebooting https://reviews.llvm.org/D28990
I've included AutoUpgrade changes to modify the data layout to satisfy the compatible layout check. But this does mean alloca, loads, stores, etc in old IR will automatically get this new alignment.
This should fix PR46320.

MSVC currently doesn't support 80 bits long double. ICC supports it when
the option `/Qlong-double` is specified. Changing the alignment of f80
to 16 bytes so that we can be compatible with ICC's option.

Summary:
Add function to AutoUpgrade to change the datalayout of old X86 datalayout strings.
This adds "-p270:32:32-p271:32:32-p272:64:64" to X86 datalayouts that are otherwise valid
and don't already contain it.
This also removes the compatibility changes in https://reviews.llvm.org/D66843.
Datalayout change in https://reviews.llvm.org/D64931.
