Verifier: Set --verify-debug-info=true by default
r186634 started verifying debug info, and r194986 disabled it by default
because it was too expensive to run the checks on every function (since
most of the graph was reachable from each function).
r206300 moved the checks to module-level to make it cheaper, but there
was already quite a bit of testcase bitrot (and the verifier would only
print `<badref>`) so I guess no one had time to turn it back on.
This does just that. Upgrade scripts this past autumn and winter
probably fixed some of the bitrot, and this weekend I fixed the verifier
output (r232275, r232417, r232418) and thusly the remaining failing
testcases (r232290, r232415).

[libcxx] Move tuple_size and tuple_element overloads for pair and array out of !defined(_LIBCPP_HAS_NO_VARIADICS) block.
Summary:
There is no reason to guard `tuple_size`, `tuple_element` and `get<I>(...)` for pair and array inside of `<__tuple>` so that they are only available when we have variadic templates.
This requires there be redundant declarations and definitions. It also makes it easy to get things wrong.
For example the following code should compile (and does in c++11).
```
#define _LIBCPP_HAS_NO_VARIADICS
#include <array>
int main()
{
static_assert((std::tuple_size<std::array<int, 10> volatile>::value == 10), "");
}
```
This patch lifts the non-variadic parts of `tuple_size`, `tuple_types`, and `get<I>(...)` to the top of `<__tuple>` where they don't require variadic templates. This patch also removes `<__tuple_03>` because there is no longer a need for it.

AsmWriter: Assert on unresolved metadata nodes
Assert that `MDNode::isResolved()`. While in theory the `Verifier`
should catch this, it doesn't descend into all debug info, and the
`DebugInfoVerifier` doesn't call into the `Verifier`. Besides, this
helps to catch bugs when `-disable-verify=true`.
Note that I haven't come across a place where this fails with clang
today, so no testcase.

Verifier: Don't call debug info verifier if the module is broken
If `Verifier` has already found a failure, don't call
`DebugInfoVerifier`. The latter sometimes crashes in `DebugInfoFinder`
when the former would give a nice message. The only two cases I found
it crashing are explicit verifier tests I've added:
- test/Verifier/llvm.dbg.declare-expression.ll
- test/Verifier/llvm.dbg.value-expression.ll
However, I assume frontends with bugs will create invalid IR as well.
IMO, the `DebugInfoVerifier` should never crash (instead, it should fail
to verify), but subtleties like that will be easier to work out once
it's enabled again.
This is part of PR22777.

DebugInfo: Fix testcases that fail -verify-debug-info=true
As part of PR22777, fix testcases that fail the debug info verifier.
The changes fall into the following categories:
- Empty `filename:` fields in `MDFile`s. Compile units and some types
require non-empty filenames. A number of testcases have empty
filenames, probably due to hand-reduction of testcases.
- Not-quite empty arrays: `!{i32 0}`. This used to be equivalent in
the debug info schema to `!{}`. They cause problems for
`!MDSubroutineType`'s `types:` array, since it requires all operands
to be valid types. (Note that `!{null}` is the correct type array
for functions that take no arguments and return `void`.)
- Significantly bitrotted testcases. Nodes got left behind a few
upgrades ago because of missing or invalid tags.

[ELF] Use pcrel format for eh_frame_ptr field encoding
The `eh_frame_ptr` field in the `.eh_frame_hdr` section contains an address
of the `.eh_frame` section. Using an absolute 32-bit format for encoding
of this field does not work for 64-bit targets. It is better to use a
relative format because it covers both 32-bit and 64-bit cases. Sure
this work if a distance between `.eh_frame_hdr` and `.eh_frame` sections
is less than 4 Gb but it is a rather correct assumption.

IR: Take advantage of -verify checks for MDExpression
Now that we check `MDExpression` during `-verify` (r232299), make
the `DIExpression` wrapper more strict:
- remove redundant checks in `DebugInfoVerifier`,
- overload `get()` to `cast_or_null<MDExpression>` (superseding
`getRaw()`),
- stop checking for null in any accessor, and
- remove `DIExpression::Verify()` entirely in favour of
`MDExpression::isValid()`.
There is still some logic in this class, mostly to do with high-level
iterators; I'll defer cleaning up those until the rest of the wrappers
are similarly strict.
