Summary:
Code completion scoring was embedded in CodeComplete.cpp, which is bad:
- awkward to test. The mechanisms (extracting info from index/sema) can be
unit-tested well, the policy (scoring) should be quantitatively measured.
Neither was easily possible, and debugging was hard.
The intermediate signal struct makes this easier.
- hard to reuse. This is a bug in workspaceSymbols: it just presents the
results in the index order, which is not sorted in practice, it needs to rank
them!
Also, index implementations care about scoring (both query-dependent and
independent) in order to truncate result lists appropriately.
The main yak shaved here is the build() function that had 3 variants across
unit tests is unified in TestTU.h (rather than adding a 4th variant).

This is a simple hack based on what's proposed in D37686, but we can extend it if needed in follow-ups.
It gets us most of the FMF functionality that we want without adding any state bits to the flags. It
also intentionally leaves out non-FMF flags (nsw, etc) to minimize the patch.
It should provide a superset of the functionality from D46563 - the extra tests show propagation and
codegen diffs for fcmp, vecreduce, and FP libcalls.
The PPC log2() test shows the limits of this most basic approach - we only applied 'afn' to the last
node created for the call. AFAIK, there aren't any libcall optimizations based on the flags currently,
so that shouldn't make any difference.

When two interposable functions are merged, we cannot replace
uses and have to emit calls to a common internal function. However,
writeThunk() will not actually emit a thunk if the function is too
small. This leaves us in a broken state where mergeTwoFunctions
already rewired the functions, but writeThunk doesn't do anything.
This patch changes the implementation so that:
* writeThunk() does just that.
* The direct replacement of calls is moved into mergeTwoFunctions()
into the non-interposable case only.
* isThunkProfitable() is extracted and will be called for
the non-iterposable case always, and in the interposable case
only if uses are still left after replacement.
This issue has been introduced in https://reviews.llvm.org/D34806,
where the code for checking thunk profitability has been moved.

Most of the handling is pretty straightforward; fetch the default
memory flags for the specific resource type before parsing the flags
and apply them on top of that, except that some flags imply others
and some flags clear more than one flag.
For icons and cursors, the flags set get passed on to all individual
single icon/cursor resources, while only some flags affect the icon/cursor
group resource.
For stringtables, the behaviour is pretty simple; the first stringtable
resource of a bundle sets the flags for the whole bundle.
The output of these tests match rc.exe byte for byte.
The actual use of these memory flags is deprecated and they have no
effect since Win16, but some resource script files may still happen
to have them in place.

Previously these fields were only read from this header for cursors,
while Planes was hardcoded to 1 for icons (with a comment that it was
unknown why this was needed) and BitCount was left at the value
read originally in the RESDIRENTRY.
This fixes the single byte that was differing for the icon/cursor test
compared to rc.exe.
This is based on research/testing by Nico Weber.
