Summary:
The decorator @expectedFailureGcc was at the wrong place skipping this
test all together. This patch removes it and adds skipIfGcc at the right
place.

There's only one user of the various `DIObjCProperty::is*Property()`
accessors -- `DwarfUnit::constructTypeDIE()` -- and it's just using the
reverse logic to reconstruct the bitfield. Drop this API and simplify
the only caller.

This keeps the program and JIT output in sync, enabling FileCheck to test the
order of target program and JIT events.
In particular we can now test that main is not compiled until after the global
constructor has run.

These accessors in `DIDerivedType` should only be called when `DbgNode`
really is a `MDDerivedType`, not just a `MDDerivedTypeBase`. Assume
that it is.

Combine something like:
(v8i8 concat_vectors (v2i8 bitcast (i16)) x4)
into:
(v8i8 (bitcast (v4i16 BUILD_VECTOR (i16) x4)))
If any of the scalars are floating point, use that throughout.

DynamicFile and ELFFile are instantiated for four different types,
ELF{32,64}{BE,LE}. Because the classes are instantiated in each
compilation unit, including the header file makes object files
10MB larger.
On Windows, issue of excessive template instantiation is critical,
since the regular COFF file supports only up to 65534 sections.
(We could use the extended COFF file format, but generating that
much COMDAT sections is not a good thing in the first place
because it means long compile time and long link time.)
I confirmed that this change makes AArch64TargetHandler.cpp.o
from 21MB to 8.5MB. It feels still too large, but I think it's
a good start.

-Wrange-loop-analysis is a subgroup of -Wloop-analysis and will warn when
a range-based for-loop makes copies of the elements in the range. If possible,
suggest the proper type to prevent copies, or the non-reference to help
distinguish copy versus non-copy forms. Existing warnings in -Wloop-analysis
are moved to -Wfor-loop-analysis, also a subgroup of -Wloop-analysis.

This is almost NFC, but I'm removing some assertions against `nullptr`.
The assertions aren't worth all that much since we'll typically get
segfaults at the same site (and I imagine ASan catches this sort of
thing), and besides: the whole idea is to replace the `DIDescriptor`
hierarchy with raw pointers to the new one.

Instead of calling the somewhat confusingly-named
`DIVariable::isInlinedFnArgument()`, do the check directly here.
There's possibly a small functionality change here: instead of
`dyn_cast<>`'ing `DV->getScope()` to `MDSubprogram`, I'm looking up the
scope chain for the actual subprogram. I suspect that this is a no-op
for function arguments so in practise there isn't a real difference.
I've also added a `FIXME` to check the `inlinedAt:` chain instead, since
I wonder if that would be more reliable than the
`MDSubprogram::describes()` function.
Since this was the only user of `DIVariable::isInlinedFnArgument()`,
delete it.
llvm-svn: 234799
`DIGlobalVariable::getGlobal()` isn't really helpful, it just does a
`dyn_cast_or_null<>`. Simplify its only user by doing the cast directly
and delete the code.
llvm-svn: 234796
The only difference between the two is a `dyn_cast<>` to
`GlobalVariable`. If optimizations have left anything behind when a
global gets replaced, then it doesn't seem like the debug info is dead.
I can't seem to find an optimization that would leave behind a
non-`GlobalVariable` without nulling the reference entirely, so I
haven't added a testcase (but I'll be deleting `getGlobal()` in a future
commit).
llvm-svn: 234792
Use early-return style that's preferred in LLVM and updating the naming in places I touched with other changes in the last few days. Hopefully, NFC.

We use dummy calls to adjust the liveness of values over statepoints in the midst of the insertion. If there are no values which need held live, there's no point in actually inserting the holder.
llvm-svn: 234779
I don't really like this function at all -- I think it should be as
simple as `return getFunction() == F` -- but for now this seems like the
best we can do.

This reverts commit r234717, reapplying r234698 (in spirit).
As described in r234717, the original `Verifier` check had a
use-after-free. Instead of storing pointers to "interesting" debug info
intrinsics whose bit piece expressions should be verified once we have
typerefs, do a second traversal. I've added a testcase to catch the
`llc` crasher.
Original commit message:
Verifier: Check for incompatible bit piece expressions
Convert an assertion into a `Verifier` check. Bit piece expressions
must fit inside the variable, and mustn't be the entire variable.
Catching this in the verifier will help us find bugs sooner, and makes
`DIVariable::getSizeInBits()` dead code.
