Summary:
For functions there is a check to not duplicate the declaration if it is in a
record (class). For function templates there was no similar check, if a
template (in the same class) was imported multiple times the
FunctionTemplateDecl was created multiple times with the same templated
FunctionDecl. This can result in problems with the declaration chain.

Function MipsAsmParser::expandMemInst() did not properly handle
instruction `sc` with a symbol as an argument because first argument
would be counted twice. We add additional checks and handle this case
separately.

- Remove support for non-recursive mutexes. This was unused.
- The std::recursive_mutex is now created/destroyed unconditionally.
Locking is still only done if threading is enabled.
- Alias SmartScopedLock to std::lock_guard.
This should make no semantic difference on the existing APIs.

In particular this helps the SSE vector shift cvttps2dq+add+shl pattern by avoiding the need for zeros in shuffle style extensions to vXi32 types as we'll be shifting out those bits anyway

Summary:
While removing -z separate-code makes lld produce place the code at the
end of a segment right now, it's possible that future changes to the
linker will change that, thereby removing the coverage for the changes
in r367983. This patch adds a linker script to one of the line table
tests, which ensures that the code (and its line table) will be placed
at the very end of a module.

Summary:
Explicitly code-sign the LLDB.framework copy of debugserver in the build-tree. This is necessary, because the Xcode-specific logic in `llvm_codesign` [1] has the side-effect that Xcode code-signs after post-build steps (here: after copying debugserver over into the framework). The special case for Xcode was necessary to avoid double-signing errors in the past (see D55116 and D55816).

Summary:
Hard code gsl::Owner/gsl::Pointer for std types. The paper mentions
some types explicitly. Generally, all containers and their iterators are
covered. For iterators, we cover both the case that they are defined
as an nested class or as an typedef/using. I have started to test this
implementation against some real standard library implementations, namely
libc++ 7.1.0, libc++ 8.0.1rc2, libstdc++ 4.6.4, libstdc++ 4.8.5,
libstdc++ 4.9.4, libstdc++ 5.4.0, libstdc++ 6.5.0, libstdc++ 7.3.0,
libstdc++ 8.3.0 and libstdc++ 9.1.0.
The tests are currently here
https://github.com/mgehre/llvm-project/blob/lifetime-ci/lifetime-attr-test.shhttps://github.com/mgehre/llvm-project/blob/lifetime-ci/lifetime-attr-test.cpp
I think due to their dependency on a standard library, they are not a good fit
for clang/test/. Where else could I put them?

This was initially committed in r368059 but got reverted in r368084
because there was a faulty logic in how the shift amounts type mismatch
was being handled (it simply wasn't).
I've added an explicit bailout before we SimplifyAddInst() - i don't think
it's designed in general to handle differently-typed values, even though
the actual problem only comes from ConstantExpr's.
I have also changed the common type deduction, to not just blindly
look past zext, but try to do that so that in the end types match.

Mips/elf-flags.yaml and Mips/elf-abi.yaml are tests that intention was to
show that yaml2obj/obj2yaml are able to read/dump MIPS specific e_flags.
They were not complete, contained an excessive YAML parts and were placed
at a wrong location.
I removed them and created the obj2yaml/elf-mips-eflags.yaml instead.

When e_shstrndx is equal to SHN_XINDEX,
the index of the section string table section should
be taken from the sh_link field of the section
header at index 0.
If sh_link is broken, e.g. contains an index that is
larger than number of sections, then error is reported.
This error message was untested before.

Currently we check whether LR is stored/loaded to/from inbetween the
loop decrement and loop end pseudo instructions. There's two problems
here:
- It relies on all load/store instructions being labelled as such in
tablegen.
- Actually any use of loop decrement is troublesome because the value
doesn't exist!
So we need to check for any read/write of LR that occurs between the
two instructions and revert if we find anything.

If this patch causes a failure then please before reverting do report
the IR that hits the assertion and try identifying the pass that

Summary:
This pass tries to remove Global Variables, as well as their derived uses. For example if a variable `@x` is used by `%call1` and `%call2`, both these uses and the definition of `@x` are deleted. Moreover if `%call1` or `%call2` are used elsewhere those uses are also deleted, and so on recursively.
I'm still uncertain if this pass should remove derived uses, I'm open to suggestions.
