[MergeFunctions] Fix merging of small weak functions

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.

[llvm-rc] Add support for parsing memory flags

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.

[CommandLine] Error message for incorrect PositionalEatArgs usage

Summary:
bugpoint has several options specified as `PositionalEatArgs` to pass
options through to the underlying tool, e.g. `-tool-args`. The `-help`
message suggests the usage is: `-tool-args=<string>`. However, this is
misleading, because that's not how these arguments work. Rather than taking
a value, the option consumes all positional arguments until the next
recognized option (or all arguments if `--` is specified at some point).
To make this slightly clearer, instead print the help as:
```
  -tool-args <string>...                            - <tool arguments>...
```
Additionally, add an error if the user attempts to use a `PositionalEatArgs`
argument with a value, instead of silently ignoring it. Example:
```
./bin/bugpoint -tool-args=-mpcu=skylake-avx512
bugpoint: for the -tool-args option: This argument does not take a value.
    Instead, it consumes any positional arguments until the next recognized option.

is easy. Move this pass to being R600 only for now.

This pass does pass all the unit tests, however clang
no longer generates code that looks like the unit test
input, so fixing the pass requires fixing the tests and

As reported in PR37264, in some cases the X86 Domain Reassignment
`runOnMachineFunction()` is called twice.  Because it only deletes the
`.second` members of its `InstrConverterBaseMap`, and does not clean up
the map itself, this can lead to double frees and crashes.

safely be reinitialized and its members re-deleted for each X86 Domain
Reassignment pass.

Summary:
Currently the order of blocks returned by `IDF::calculate` can be
non-deterministic. This was discovered in several attempts to enable
SSAUpdaterBulk for JumpThreading (which led to miscompare in bootstrap between
stage 3 and stage4). Originally, the blocks were put into a priority queue with
a depth level as their key, and this patch adds a DFSIn number as a second key
to specify a deterministic order across blocks from one level.

The solution was suggested by Daniel Berlin.
