Tag types like stucts or enums didn't have a declaration attached to
them. The source locations are present in the IPI stream in
`LF_UDT_MOD_SRC_LINE` records:
```
0x101F | LF_UDT_MOD_SRC_LINE [size = 18, hash = 0x1C63]
udt = 0x1058, mod = 3, file = 1, line = 0
0x2789 | LF_UDT_MOD_SRC_LINE [size = 18, hash = 0x1E5A]
udt = 0x1253, mod = 35, file = 93, line = 17069
```
The file is an ID in the string table `/names`:
```
ID | String
1 | '\<unknown>'
12 | 'D:\a\_work\1\s\src\ExternalAPIs\WindowsSDKInc\c\Include\10.0.22621.0\um\wingdi.h'
93 | 'D:\a\_work\1\s\src\ExternalAPIs\WindowsSDKInc\c\Include\10.0.22621.0\um\winnt.h'
```
Here, we're not interested in `mod`. This would indicate which module
contributed the UDT.
I was looking at Rustc's PDB and found that it uses `<unknown>` for some
types, so I added a check for that.
This makes two DIA PDB shell tests to work with the native PDB plugin.

%T has been deprecated for about seven years, mostly because it is not
unique to each test which can lead to races. This patch updates the few
remaining tests in lldb that use %T to not use it (either directly using
files or creating their own temp dir). The eventual goal is to remove
support for %T from llvm-lit given few tests use it and it still has
racey behavior.
This patch errors on the side of creating new temp dirs even when not
strictly necessary to avoid needing to update filenames inside filecheck
matchers.

Since the remote Shell test execution feature was added, these tests
should now be disabled on Windows target instead of Windows host.
It should fix failures on
https://lab.llvm.org/staging/#/builders/197/builds/76.

The pdb lldb tests do not work correctly with both the VS2019 and VS2017 toolsets at the moment. This change updates several of the tests to work with both toolsets. Unfortunately, this makes the tests suboptimal for both toolsets, but we can update them to be better for VS2019 once we officially drop VS2017. This change is meant to bridge the gap until the update happens, so that the buildbots can work with either toolset.

The original patch got reverted because it broke `check-lldb` on a clean
build. This fixes that.

as it appears to have broken check-lldb.
This reverts r374184 (git commit 22314179f0660c172514b397060fd8f34b586e82)

LLDB has three major testing strategies: unit tests, tests that exercise
the SB API though dotest.py and what we currently call lit tests. The
later is rather confusing as we're now using lit as the driver for all
three types of tests. As most of this grew organically, the directory
structure in the LLDB repository doesn't really make this clear.
The 'lit' tests are part of the root and among these tests there's a
Unit and Suite folder for the unit and dotest-tests. This layout makes
it impossible to run just the lit tests.
This patch changes the directory layout to match the 3 testing
strategies, each with their own directory and their own configuration
file. This means there are now 3 directories under lit with 3
corresponding targets:
- API (check-lldb-api): Test exercising the SB API.
- Shell (check-lldb-shell): Test exercising command line utilities.
- Unit (check-lldb-unit): Unit tests.
Finally, there's still the `check-lldb` target that runs all three test
suites.
Finally, this also renames the lit folder to `test` to match the LLVM
repository layout.
