This is a very thin wrapper over a std::vector<DWARFDIE> and does
not seem to provide any real value over just using a container
directly.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This moves the following classes from Core -> Utility.
ConstString
Error
RegularExpression
Stream
StreamString
The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes. So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

lldb::user_id_t out to the rest of LLDB:
1 - DWARF in .o files with debug map in executable: we would place the compile unit index in the upper 32 bits of the 64 bit value and the lower 32 bits would be the DIE offset
2 - DWO: we would place the compile unit offset in the upper 32 bits of the 64 bit value and the lower 32 bits would be the DIE offset
There was a mixing and matching of this and it wasn't done consistently.
Major changes include:
The DIERef constructor that takes a lldb::user_id_t now requires a SymbolFileDWARF:
DIERef(lldb::user_id_t uid, SymbolFileDWARF *dwarf)
It is needed so that it can be decoded correctly. If it is DWARF in .o files with debug map in executable, then we get the right compile unit from the SymbolFileDWARFDebugMap, otherwise, we use the compile unit offset and DIE offset for DWO or normal DWARF.
The function:
lldb::user_id_t DIERef::GetUID() const;
Now becomes
lldb::user_id_t DIERef::GetUID(SymbolFileDWARF *dwarf) const;
Again, we need the DWARF file to encode it correctly.
This removes the need for "lldb::user_id_t SymbolFileDWARF::MakeUserID() const" and for bool SymbolFileDWARF::UserIDMatches (lldb::user_id_t uid) const". There were also many places were doing things inneficiently like:
1 - encode a dw_offset_t into a lldb::user_id_t
2 - call the public SymbolFile interface to resolve types using the lldb::user_id_t
3 - This would then decode the lldb::user_id_t into a DIERef, and then try to find that type.
There are many places that are now doing this more efficiently by storing DW_AT_type form values as DWARFFormValue objects and then making a DIERef from them and directly calling the underlying function to resolve the lldb_private::Type, lldb_private::CompilerType, lldb_private::CompilerDecl, lldb_private::CompilerDeclContext.
If there are any regressions in DWARF with DWO, we will need to fix any issues that arise since the original patch wasn't functional for the much more widely used DWARF in .o files with debug map.

outside of DWARFDebugInfoEntry of DWARFCompileUnit should use DWARFDIE only.

Added a new class called DWARFDIE that contains a DWARFCompileUnit and DWARFDebugInfoEntry so that these items always stay together.
There were many places where we just handed out DWARFDebugInfoEntry pointers and then use them with a compile unit that may or may not be the correct one. Clients outside of DWARFCompileUnit and DWARFDebugInfoEntry should all be dealing with DWARFDIE instances instead of playing with DWARFCompileUnit/DWARFDebugInfoEntry pairs manually.
This paves to the way for some modifications that are coming for DWO.
