[gn build] port a8025e06fc0f more

to be passes as -I flag now.

[CMake] Installable find modules for terminfo and libffi

Improves cross-distro portability of LLVM cmake package by resolving paths for
terminfo and libffi via import targets.

When LLVMExports.cmake is generated for installation, it contains absolute
library paths which are likely to be a common cause of portability issues. To
mitigate this, the discovery logic for these dependencies is refactored into
find modules which get installed alongside LLVMConfig.cmake. The result is
cleaner, cmake-friendly management of these dependencies that respect the
environment of the LLVM package importer.

[lld-macho] Unreferenced weak dylib symbols shouldn't fetch archive symbols

We were fetching archive symbols too eagerly, bloating binary size as well as
just screwing up binaries that expected to look up certain symbols only at
runtime.

[GlobalISel] Allow DBG_VALUE to use undefined vregs before LiveDebugValues.

Expanding on D109750.

Since `DBG_VALUE` instructions have final register validity determined in
`LDVImpl::handleDebugValue`, there is no apparent reason to immediately prune
unused register operands as their defs are erased. Consequently, this renders
`MachineInstr::eraseFromParentAndMarkDBGValuesForRemoval` moot; gaining a
substantial performance improvement.

The only necessary changes involve making relevant passes consider invalid
DBG_VALUE vregs uses as valid.
