Relands #149701 which was reverted in
https://github.com/llvm/llvm-project/commit/185ae5cdc695248b58ae017508cc764c19bee5b7
because it broke demangling of Itanium symbols on i386.
The last commit in this PR adds the fix for this (discussed in #160930).
On x86 environments, the prefix of `__cdecl` functions will now be
removed to match DWARF. I opened #161676 to discuss this for the other
calling conventions.

This broke demangling of Itanium symbols on i386.

Before, functions created using the NativePDB plugin would not know
about their mangled name. This showed when printing a stacktrace. There,
only the function name was shown. For
https://github.com/llvm/llvm-project/issues/143149, the mangled function
name is required to separate different parts.
This PR adds that name if available.
The Clang AST nodes also take in a mangled name, which was previously
unset. I don't think this unblocks anything further, because Clang can
mangle the function anyway.

Lit allows you to set environment variables for all tests in a directory
using a `lit.local.cfg` file. Do this for the PDB and NativePDB tests.

|
These test don't execute the binaries they build, and so they don't need
to build for the host. By hardcoding the target, we don't have do xfail
or skip them for targets which don't have the appropriate support in
clang(-cl).
|
|
Following test cases need minor adjustment in order to accomodate xfail
decorator:
lldb/test/Shell/SymbolFile/NativePDB/break-by-line.cpp
lldb/test/Shell/SymbolFile/NativePDB/source-list.cpp

NativePDB tests fail on arm-linux buildbot. clang-cl driver crashes with
-m32 option. Bug files http://llvm.org/pr45867

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.
