Track and print the number of tests that were discovered but not
executed due to test selection options:
  * --filter (regex filter)
  * --max-tests (limits number of tests)
  * sharding feature

With this change all discovered tests are accounted for: every
discovered test is included in one of the counts printed in the summary.

The setting of `MCAsmInfo` properties for XCOFF got split between
`MCAsmInfoXCOFF` and `PPCXCOFFMCAsmInfo`. Except for the properties that
are dependent on the target information being passed via the
constructor, the properties being set in `PPCXCOFFMCAsmInfo` had no
fundamental reason for being treated as specific for XCOFF on PowerPC.
Indeed, the property that might be considered more specific to PowerPC,
`NeedsFunctionDescriptors`, was set in `MCAsmInfoXCOFF`.

XCOFF being specific to PowerPC anyway, this patch consolidates the
setting of the properties into `MCAsmInfoXCOFF` except for the cases
that are dependent on the information provided via the
`PPCXCOFFMCAsmInfo` constructor.

This patch also reorders the assignments to the fields to match the
declaration order in `MCAsmInfo`.

Summary:
This patch splits mostly unrelated size constants into separate
constexpr variables, sets explicit underlying types for the enumerations
to match the fields they are used for, and improves various comments.

This patch also replaces `<cname>` headers with `<name.h>` headers to
match the usage of the declared names as global namespace members in the
file.

Android doesn't have a libgcc_s and uses libgcc instead, so adjust the
build accordingly. This matches compiler-rt's build setup. libc++abi and
libunwind were already checking for libgcc but in a different context.
This change makes them search only for libgcc on Android now, but the
code to link against libgcc if it were present was already there.

Summary:
This revision cleans up a layer of complexity in ScopedContext and uses InsertGuard instead of previously manual bookkeeping.
The method `getBuilder` is renamed to `getBuilderRef` and spurious copies of OpBuilder are tracked.

This results in some canonicalizations not happening anymore in the Linalg matmul to vector test. This test is retired because relying on DRRs for this has been shaky at best. The solution will be better support to write fused passes in C++ with more idiomatic pattern composition and application.

Reverting part of https://reviews.llvm.org/D79137 which caused an
failure in an ObjectYAML test.

This cleanup was suggested as part of D78458.

In D74183 clang started emitting alignment for sret parameters
unconditionally. This caused a 1.5% compile-time regression on
tramp3d-v4. The reason is that we now generate many instance of IR like

    %ptrint = ptrtoint %class.GuardLayers* %guards_m to i64
    %maskedptr = and i64 %ptrint, 3
    %maskcond = icmp eq i64 %maskedptr, 0
    tail call void @llvm.assume(i1 %maskcond)

to preserve the alignment information during inlining. Based on IR
analysis, these assumptions also regress optimization. The attached
phase ordering test case illustrates two issues: One are instruction
count based optimization heuristics, which are affected by the four
additional instructions of the assumption. The other is blocking of
SROA due to ptrtoint casts (PR45763).

We already encountered the same problem in Rust, where we (unlike
Clang) generally prefer to emit alignment information absolutely
everywhere it is available. We were only able to do this after
hardcoding -preserve-alignment-assumptions-during-inlining=false,
because we were seeing significant optimization and compile-time
regressions otherwise.

This patch disables -preserve-alignment-assumptions-during-inlining
by default, because we should not be punishing people for adding
more alignment annotations.

Once the assume bundle work shakes out and we can represent (and use)
alignment assumptions using assume bundles, it should be possible to
re-enable this with reduced overhead.

Currently, `SBCommandInterpreterRunOptions` is defined in
`SBCommandInterpreter.h`. Given that the options are always passed by
reference, a forward declaration is sufficient.

That's not the case for `SBCommandInterpreterRunResults`, which we need
for a new overload for `RunCommandInterpreter` and that returns this new
class by value. We can't include `SBCommandInterpreter.h` because
`SBCommandInterpreter::GetDebugger()` returns SBDebugger by value and
therefore needs a full definition.

This patch moves the definition of `SBCommandInterpreterRunOptions` into
a new header. In a later patch,  `SBCommandInterpreterRunResults` will
be defined in there as well, solving the aforementioned problem.

It seems like only the unittests are building with
BUILD_WITH_INSTALL_RPATH set to OFF. Of course when I did my last change
I only ran check-lldb-unit. Not sure why this difference exists, why
would you even install the unittest?

For the LLDB framework we do need different build and install RPATHs.
Currently that logic lives downstream. I plan to upstream that in the
near future. For now I'm just trying to make it possible to run the
test.
