Summary: Refactor the current global header iteration to be callback-based, and add a feature that reports the size of the global variable during reporting. This allows binaries without symbols to still report the size of the global variable, which is always available in the HWASan globals PT_NOTE metadata.

Summary:
Fixes up two small issues with the gn build.
1 - Ensures that the correct ldflag `-pthread` is provided, not just linking the library.
2 - Ensures that libraries are linked in the same group as the dependencies. This fixes a problem where system libraries (libc) are involved in a link-order dependency that's not being fulfilled.

Having the input dumped on failure seems like a better
default: I debugged FileCheck tests for a while without knowing
about this option, which really helps to understand failures.
Remove `-dump-input-on-failure` and the environment variable
FILECHECK_DUMP_INPUT_ON_FAILURE which are now obsolete.

Summary: Note to downstream target maintainers: this might silently change the semantics of your code if you override `TargetLowering::HandleByVal` without marking it `override`.
This patch is part of a series to introduce an Alignment type.
See this thread for context: http://lists.llvm.org/pipermail/llvm-dev/2019-July/133851.html

Improve consistency when printing test results:
Previously we were using different labels for group names (the header
for the list of, e.g., failing tests) and summary count lines. For
example, "Failing Tests"/"Unexpected Failures". This commit changes lit
to label things consistently.
Improve wording of labels:
When talking about individual test results, the first word in
"Unexpected Failures", "Expected Passes", and "Individual Timeouts" is
superfluous. Some labels contain the word "Tests" and some don't.
Let's simplify the names.
Before:
```
Failing Tests (1):
...
Expected Passes : 3
Unexpected Failures: 1
```
After:
```
Failed Tests (1):
...
Passed: 3
Failed: 1
```

When `variable_ops` is specified in `InOperandList` of instruction,
it behaves as expected, i.e., does not count as operand.
So for `(ins variable_ops)` instruction description will have 0
operands. However when used in OutOperandList it is counted as
operand. So `(outs variable_ops)` results in instruction with
one def.
This patch makes behavior of `variable_ops` in `out` list to match
that of `in` list.

lld's symbol resolution algorithm makes it not depend on
the order of object files and libraries, but ld.bfd and
gold require listing dependencies later on the link line.
Put {{libs}} after {{inputs}} so that e.g. -lpthreads
appears after the object files, not before it.

This is effectively reverting rGbfdc2552664d to avoid test churn
while we figure out a better way forward.
We at least salvage the warning on name conflict from that patch
though.
If we change the default string again, we may want to mass update
tests at the same time. Alternatively, we could live with the poor
naming if we change -instnamer.
This also adds a test to LLVM as suggested in the post-commit
review. There's a clang test that is also affected. That seems
like a layering violation, but I have not looked at fixing that yet.

As discussed in PR45951:
https://bugs.llvm.org/show_bug.cgi?id=45951
There's a potential name collision between update_test_checks.py and -instnamer
and/or manually-generated IR test files because all of them try to use the
variable name that should never be used: "tmp".
This patch proposes to reduce the odds of collision and adds a warning if we
detect the problem. This will cause regression test churn when regenerating
CHECK lines on existing files.
