r214242 was subtle enough it really deserves a targeted test with
comments. This adds some global variables that trigger the relevant
code path. Sorry this wasn't committed with the fix.

To avoid unnecessary forward references, the reader doesn't process
initializers of `GlobalValue`s until after the constant pool has been
processed, and then in reverse order. Model this when predicting
use-list order. This gets two more Bitcode tests passing with
`llvm-uselistorder`.
Part of PR5680.

This moves some tests around to make it clearer what's being tested,
and adds very rudimentary comment syntax to the text input format to
make specifying this kind of test a little bit simpler.

This patch reduces the complexity of the two inner loops in order to speed up
the loading of coverage data for very large functions.

MSVC [1] thinks `UseListShuffleVector` needs a copy constructor, but I
don't. Let's see if being explicit about `UseListOrder` is convincing.

This is more convenient for callers. No functionality change, this will
be used in a next patch to the gold plugin.

Remove the copy constructor added in r214178 to appease MSVC17 since it
shouldn't be called at all. My guess is that explicitly deleting it
will make the compiler happy. To round out the operations I've also
deleted copy assignment and added move assignment. Otherwise no
functionality change.

full paths for its first argument.
This allows us to remove the annoying sed lines in the test cases, and write
direct references to file names in stub_addr calls (rather than <filename>
placeholders).

This will let users in other libraries know which error occurred. In particular,
it will be possible to check if the parsing failed or if the file is not
bitcode.

Per feedback on r214111, we are going to use null to represent unspecified
parameter. If the type array is {null}, it means a function that returns void;
If the type array is {null, null}, it means a variadic function that returns
void. In summary if we have more than one element in the type array and the last
element is null, it is a variadic function.

The test being performed is just an approximation anyway, so it really
shouldn't crash when things don't go entirely as expected.
Should fix PR20474.

We need to make sure we use the softened version of all appropriate operands in
the libcall, or things go horribly wrong. This may entail actually executing a
1-stage softening.
