If dependent types appear in pointers or references we allow addr
space deduction because the addr space in template argument will
belong to the pointee and not the pointer or reference itself.
We also don't diagnose addr space on a function return type after
template instantiation. If any addr space for the return type was
provided on a template parameter this will be diagnosed during the
parsing of template definition.

We currently emit the option groups twice if Groups<[1,2,3]> is
used in the tablegen. This leads to compilation errors. This
patch just removes the line that accidentially emits the option
group a second time.

I'm not convinced the code this calls is properly vetted for
vXi1 vectors. Experimental vector widening legalization testing
for D55251 is now hitting an assertion failure inside
EltsFromConsecutiveLoads. This is occurring from a v2i1 load
having a store size different than its VT size. Hopefully
this commit will keep such issues from happening.

When code relaxation is enabled many RISC-V fixups are not resolved but
instead relocations are emitted. This happens even for DWARF debug
sections. Therefore, to properly support the parsing of DWARF debug info
we need to be able to resolve RISC-V relocations. This patch adds:
* Support for RISC-V relocations in RelocationResolver
* DWARF support for two relocations per object file offset
* DWARF changes to support relocations in more DIE fields
The two relocations per offset change is needed because some RISC-V
relocations (used for label differences) come in pairs.
Relocations can also be emitted for DWARF fields where relocations were
not yet evaluated. Adding relocation support for some of these fields is
essencial. On the other hand, LLVM currently emits RISC-V relocations
for fixups that could be safely evaluated, since they can never be
affected by code relaxations. This patch also adds relocation support
for the fields affected by those extraneous relocations (the DWARF unit
entry Length, and the DWARF debug line entry TotalLength and
PrologueLength), for testing purposes.

TableGen is a host tool and requires a native variant for every build.
While building as a part of llvm this is trivial and llvm handles it.
However, building standalone means that lldb has to handle this itself.
Add a NATIVE build variant to enable this.

It turns out that this test was only passing by accident. It was relying on
the optimizer to remove the only reference to A's vtable by realizing that
the CFI check will always fail. The vtable contains a reference to RTTI in
libc++, which will be unresolved because the C driver won't link against it.
This was found by my prototype implementation of HWASAN for globals, which
happens to end up preserving the reference.

- getCompression() used to return a PDB_SourceCompression even though
the docs for IDiaInjectedSource are explicit about the return value
being compiler-dependent. Return an uint32_t instead, and make the
printing code handle unknown values better by printing "Unknown" and
the int value instead of not printing any compression.
- Print compressed contents as hex dump, not as string.
- Add compression type "DotNet", which is used (at least) by csc.exe,
the C# compiler. Also add a lengthy comment describing the stream
contents (derived from looking at the raw hex contents long enough
to see the GUIDs, which led me to the roslyn and mono implementations
for handling this).
- The native injected source dumper was dumping the contents of the
whole data stream -- but csc.exe writes a stream that's padded with
zero bytes to the next 512 boundary, and the dia api doesn't display
those padding bytes. So make NativeInjectedSource::getCode() do the
same thing.

If a core file has an EFI version string which includes a UUID
(similar to what it returns for the kdp KDP_KERNELVERSION packet)
in the LC_IDENT or LC_NOTE 'kern ver str' load command. In that
case, we should try to find the binary and dSYM for the UUID
listed. The dSYM may have python code which knows how to relocate
the binary to the correct address in lldb's target section load
list and loads other ancillary binaries.
The test case is a little involved,
1. it compiles an inferior hello world apple (a.out),
2. it compiles a program which can create a corefile manually
with a specific binary's UUID encoded in it,
3. it gets the UUID of the a.out binary,
4. it creates a shell script, dsym-for-uuid.sh, which will
return the full path to the a.out + a.out.dSYM when called
with teh correct UUID,
5. it sets the LLDB_APPLE_DSYMFORUUID_EXECUTABLE env var before
creating the lldb target, to point to this dsym-for-uuid.sh,
6. runs the create-corefile binary we compiled in step #2,
7. loads the corefile from step #6 into lldb,
8. verifies that lldb loaded a.out by reading the LC_NOTE
load command from the corefile, calling dsym-for-uuid.sh with
that UUID, got back the path to a.out and loaded it.

The LocalStackSlotPass pre-allocates a stack protector and makes sure
that it comes before the local variables on the stack.
We need to make sure that later during PEI we don't re-allocate a new
stack protector slot. If that happens, the new stack protector slot will
end up being **after** the local variables that it should be protecting.
Therefore, we would have two slots assigned for two different stack
protectors, one at the top of the stack, and one at the bottom. Since
PEI will overwrite the assigned slot for the stack protector, the load
that is used to compare the value of the stack protector will use the
slot assigned by PEI, which is wrong.
For this, we need to check if the object is pre-allocated, and re-use
that pre-allocated slot.

Extract the sources to the GCD of the original size and target size,
padding with implicit_def as necessary.

Use an anyext to the requested type for the leftover operand to
produce a slightly wider type, and then truncate the final merge.
I have another implementation almost ready which handles arbitrary
widens, but I think it produces worse code in this example (which I
think is 90% due to not folding redundant copies or folding out
implicit_def users), so I wanted to add this as a baseline first.
