Fix infinite recursion when calling C++ template functions
Summary:
When we encounter a templated function in the debug information, we
were creating an AST that looked like this:
FunctionTemplateDecl 0x12980ab90 <<invalid sloc>> <invalid sloc> foo<int>
|-TemplateTypeParmDecl 0x12980aad0 <<invalid sloc>> <invalid sloc> class depth 0 index 0 T
|-FunctionDecl 0x12980aa30 <<invalid sloc>> <invalid sloc> foo<int> 'int (int)' extern
| |-TemplateArgument type 'int'
| `-ParmVarDecl 0x12980a998 <<invalid sloc>> <invalid sloc> t1 'int'
`-FunctionDecl 0x12980aa30 <<invalid sloc>> <invalid sloc> foo<int> 'int (int)' extern
|-TemplateArgument type 'int'
`-ParmVarDecl 0x12980a998 <<invalid sloc>> <invalid sloc> t1 'int'
Note that the FunctionTemplateDecl has 2 children which are identical (as
in have the same address). This is not what Clang is doing:
FunctionTemplateDecl 0x7f89d206c6f8 </tmp/template.cpp:1:1, line:4:1> line:2:5 foo
|-TemplateTypeParmDecl 0x7f89d206c4a8 <line:1:10, col:19> col:19 referenced typename depth 0 index 0 T
|-FunctionDecl 0x7f89d206c660 <line:2:1, line:4:1> line:2:5 foo 'int (T)'
| `-ParmVarDecl 0x7f89d206c570 <col:9, col:11> col:11 t1 'T'
`-FunctionDecl 0x7f89d206cb60 <line:2:1, line:4:1> line:2:5 used foo 'int (int)'
|-TemplateArgument type 'int'
`-ParmVarDecl 0x7f89d206ca68 <col:9, col:11> col:11 t1 'int':'int'
The 2 chidlren are different and actually repesent different things: the first
one is the unspecialized version and the second one is specialized. (Just looking
at the names shows another major difference which is that we create the parent
with a name of "foo<int>" when it should be just "foo".)
The fact that we have those 2 identical children confuses the ClangImporter
and generates an infinite recursion (reported in https://llvm.org/pr41473).
We cannot create the unspecialized version as the debug information doesn't
contain a mapping from the template parameters to their use in the prototype.
This patch just creates 2 different FunctionDecls for those 2 children of the
FunctionTemplateDecl. This avoids the infinite recursion and allows us to
call functions. As the XFAILs in the added test show, we've still got issues
in our handling of templates. I believe they are mostly centered on the fact
that we create do not register "foo" as a template, but "foo<int>". This is
a bigger change that will need changes to the debug information generation.
I believe this change makes sense on its own.

Try once more to ensure constant initializaton of ManagedStatics
First, use the old style of linker initialization for MSVC 2019 in
addition to 2017. MSVC 2019 emits a dynamic initializer for
ManagedStatic when compiled in debug mode, and according to zturner,
also sometimes in release mode. I wasn't able to reproduce that, but it
seems best to stick with the old code that works.
When clang is using the MSVC STL, we have to give ManagedStatic a
constexpr constructor that fully zero initializes all fields, otherwise
it emits a dynamic initializer. The MSVC STL implementation of
std::atomic has a non-trivial (but constexpr) default constructor that
zero initializes the atomic value. Because one of the fields has a
non-trivial constructor, ManagedStatic ends up with a non-trivial ctor.
The ctor is not constexpr, so clang ends up emitting a dynamic
initializer, even though it simply does zero initialization. To make it
constexpr, we must initialize all fields of the ManagedStatic.
However, while the constructor that takes a pointer is marked constexpr,
clang says it does not evaluate to a constant because it contains a cast
from a pointer to an integer. I filed this as:
https://developercommunity.visualstudio.com/content/problem/545566/stdatomic-value-constructor-is-not-actually-conste.html
Once we do that, we can add back the
LLVM_REQUIRE_CONSTANT_INITIALIZATION marker, and so far as I'm aware it
compiles successfully on all supported targets.

[DataFormatters] Adjusting libc++ std::list formatter to act better with pointers and references and adding a test to cover a previous related fix
Summary:
This previous fix https://github.com/llvm-mirror/lldb/commit/
5469bda296c183d1b6bf74597c88c9ed667b3145 did not have a test since we did not have a reproducer.
This is related to how formatters deal with pointers and references. The added tests both the new behavior and covers the previous bug fix as well.

[JITLink] Refer to FDE's CIE (not the most recent CIE) when parsing eh-frame.
Frame Descriptor Entries (FDEs) have a pointer back to a Common Information
Entry (CIE) that describes how the rest FDE should be parsed. JITLink had been
assuming that FDEs always referred to the most recent CIE encountered, but the
spec allows them to point back to any previously encountered CIE. This patch
fixes JITLink to look up the correct CIE for the FDE.
The testcase is a MachO binary with an FDE that refers to a CIE that is not the
one immediately proceeding it (the layout can be viewed wit
'dwarfdump --eh-frame <testcase>'. This test case had to be a binary as llvm-mc
now sorts FDEs (as of r356216) to ensure FDEs *do* point to the most recent CIE.

[scudo][standalone] Introduce the Secondary allocator
Summary:
The Secondary allocator wraps the platform allocation primitives. It is
meant to be used for larger sizes that the Primary can't fullfill, as
it will be slower, and sizes are multiple of the system page size.
This also changes some of the existing code, notably the opaque
platform data being passed to the platform specific functions: we can
shave a couple of syscalls on Fuchsia by storing additional data (this
addresses a TODO).

Kill modify-python-lldb.py
Summary:
After the last round of cleanups, this script was almost a no-op. The
only piece of functionality that remained was the one which tried to
make the swig-generated function signatures more pythonic.
The "tried" part is important here, as it wasn't doing a really good job
and the end result was not valid python nor c (e.g.,
SetExecutable(SBAttachInfo self, str const * path)).
Doing these transformations another way is not possible, as these
signatures are generated by swig, and not present in source. However,
given that this is the only reason why we need a swig post-process step,
and that the current implementation is pretty sub-optimal, this patch
simply abandons the signature fixup idea, and chooses to simplify our
build process instead.
