HotColdSplit: Convert tests to opaque pointers

For some reason the script was deleting the assume declaration in
assumption-cache-invalidation.ll, so fixed that manually.

[PM/CC1] Add -f[no-]split-cold-code CC1 option to toggle splitting

This patch adds -f[no-]split-cold-code CC1 options to clang. This allows
the splitting pass to be toggled on/off. The current method of passing
`-mllvm -hot-cold-split=true` to clang isn't ideal as it may not compose
correctly (say, with `-O0` or `-Oz`).

To implement the -fsplit-cold-code option, an attribute is applied to
functions to indicate that they may be considered for splitting. This
removes some complexity from the old/new PM pipeline builders, and
behaves as expected when LTO is enabled.

[CodeExtractor] Transfer debug info to extracted function

After extracting, fix up debug info in both the old and new functions by

1) Pointing line locations and debug intrinsics to the new subprogram
scope, and

2) Deleting intrinsics which point to values outside of the new
function.

Depends on https://reviews.llvm.org/D72795.

Testing: check-llvm, check-clang, a build of LNT in the `-Os -g` config
with "-mllvm -hot-cold-split=1" set, and end-to-end debugging of a toy
program which undergoes splitting to verify that lldb can find
variables, single step, etc. in extracted code.
