When only building targets without assembly parsers (e.g. `llvm_targets_to_build
= ["NVPTX"]`), `all_targets` is empty and causes GN to warn about an
assigned-but-unused variable.

Since these are in a custom list, `gn format` doesn't automatically sort
them.
Now their order matches the CMake build.
No additions or deletions, this just sorts the files that are there.

These lit configuration files are really Python source code. Using the
.py file extension helps editors and tools use the correct language
mode. LLVM and Clang already use this convention for lit configuration,
this change simply applies it to all of compiler-rt.

- Merge r364427 (GSYM lib) more: It was missing the new unit test
(as pointed out by llvm/utils/gn/build/sync_source_lists_from_cmake.py),
and it had some superfluous deps not present in the cmake build.
- Merge r364474 (clang DependencyScanning lib) more: The deps didn't
quite match cmake.

This allows later passes (in particular InstCombine) to optimize more
cases.
One that's important to us is `memcmp(p, q, constant) < 0` and memcmp(p, q, constant) > 0.

When I executed gn.py gen out/gn I got the following error:
ERROR at //compiler-rt/lib/builtins/BUILD.gn:162:7: Only source, header, and object files belong in the sources of a static_library. //compiler-rt/lib/builtins/emutls.c is not one of the valid types.
"emutls.c ",
^----------
See //compiler-rt/lib/BUILD.gn:3:5: which caused the file to be included.
"//compiler-rt/lib/builtins",
^---------------------------
It turns out to be that the latest gn doesn't accept ill-format file name. And the emutls.c above has a trailing space.
Remove the trailing space should work.

The NVPTX target is a bit unusual in that it's the only target without a
disassembler, and one of three targets without an asm parser (and the
first one of those three in the gn build). NVPTX doesn't have those
because it's not a binary format.
The CMake build checks for the existence of
{AsmParser,Disassembler}/CMakeLists.txt when setting
LLVM_ENUM_ASM_PARSERS / LLVM_ENUM_DISASSEBLERS
(http://llvm-cs.pcc.me.uk/CMakeLists.txt#744). The GN build doesn't want
to hit the disk for things like this, so instead I'm adding explicit
`targets_with_asm_parsers` and `targets_with_disassemblers` lists. Since
both are needed rarely, they are defined in their own gni files.

Now that the cycle between MCTargetDesc and TargetInfo is gone
(see revisions 360709 360718 360722 360724 360726 360731 360733 360735 360736),
remove the dependency from TargetInfo on MCTargetDesc:tablegen. In most
targets, this makes MCTargetDesc:tablegen have just a single use, so
inline it there.
For AArch64, ARM, and RISCV there's still a similar cycle between
MCTargetDesc and Utils, so the MCTargetDesc:tablegen indirection is
still needed there.

r363016 let lld-link and llvm-lib share the /machine: parsing code.
This lets llvm-cvtres share it as well.
Making llvm-cvtres depend on llvm-lib seemed a bit strange (it doesn't
need llvm-lib's dependencies on BinaryFormat and BitReader) and I
couldn't find a good place to put this code. Since it's just a few
lines, put it in lib/Object for now.

Users are exepcted to pass all .res files to the linker, which then
merges all the resource in all .res files into a tree structure and then
converts the final tree structure to a .obj file with .rsrc$01 and
.rsrc$02 sections and then links that.
If the user instead passes several .obj files containing such resources,
the correct thing to do would be to have custom code to merge the trees
in the resource sections instead of doing normal section merging -- but
link.exe rejects if multiple resource obj files are passed in with
LNK4078, so let lld-link do that too instead of silently writing broken
.rsrc sections in that case.
The only real way to run into this is if users manually convert .res
files to .obj files by running cvtres and then handing the resulting
.obj files to lld-link instead, which in practice likely never happens.
(lld-link is slightly stricter than link.exe now: If link.exe is passed
one .obj file created by cvtres, and a .res file, for some reason it
just emits a warning instead of an error and outputs strange looking
data. lld-link now errors out on mixed input like this.)
One way users could accidentally run into this is the following
scenario: If a .res file is passed to lib.exe, then lib.exe calls
cvtres.exe on the .res file before putting it in the output .lib.
(llvm-lib currently doesn't do this.)
link.exe's /wholearchive seems to only add obj files referenced from the
static library index, but lld-link current really adds all files in the
archive. So if lld-link /wholearchive is used with .lib files produced
by lib.exe and .res files were among the files handed to lib.exe, we
previously silently produced invalid output, but now we error out.
link.exe's /wholearchive semantics on the other hand mean that it
wouldn't load the resource object files from the .lib file at all.
Since this scenario is probably still an unlikely corner case,
the difference in behavior here seems fine -- and lld-link might have to
change to use link.exe's /wholearchive semantics in the future anyways.
Vaguely related to PR42180.

lib.exe doesn't allow creating .lib files with object files that have
differing machine types. Update llvm-lib to match.
The motivation is to make it possible to infer the machine type of a
.lib file in lld, so that it can warn when e.g. a 32-bit .lib file is
passed to a 64-bit link (PR38965).
Fixes PR38782.

clangd needs them to function properly, even though they are not
