Put RdrName in the foExt field of FieldOcc

The main purpose of this commit is to rip RdrName out of FieldOcc, in
accordance with #21592, and as a side note it has simplified the method
we use to deal with ambiguity somewhat.

To do the first, we make FieldOccs store (LIdP p) instead of always
storing Located RdrName, and moved the readername to the extension
points where necessary.

For the second, well, we just turn an ambiguous RdrName into a unbound
Name through mkUnboundName. Later during disambiguateRecordBinds of the
type checking phase, we will try and do type-directed disambiguation based
on the rdrName field (for now), so this hack works out fine.

See Note [Ambiguous FieldOcc in record updates] for more details.

There are two additional minor changes in this commit:
*  The HsRecSel constructor of HsExpr has been moved to the extension
constuctors, since its really GHC specific.
*  HsProjection no longer has a Located DotFieldOcc as a field, but just a
regular DotFieldOcc, since DotFieldOcc already wraps a located
FieldLabelString

driver: bail out when -fllvm is passed to GHC not configured with LLVM

This patch makes GHC bail out with an proper error message when it's
not configured with LLVM but users attempt to pass -fllvm, see #25011
and added comment for details.

Fixes #25011

LLVM: make SSE4.2 imply +popcnt

For consistency with the NCG as well as with Clang and GCC, we make
the SSE4.2 feature flag imply +popcnt when using the LLVM backend.

Fixes #25353

Drop obsolete libffi Makefile

This patch drops obsolete libffi Makefile from the tree, given it's
completely unused since removal of make build system in !7094.

ghc-internal: Fix incomplete matches on IOError

As noted in #25362, these incomplete matches were previously not being
warned about. They were easily addressed by use of
`GHC.Internal.Event.Windows.withException`.

Closes #25362.

compiler: Fix orientation of GHC.Hs.Doc boot file

We should be free to import things from Language.Haskell.Syntax in GHC
modules. Therefore the the boot file for the loop between ImpExp and
GHC.Hs.Doc was in the wrong place.
