Serge Pavlov 4bc0562719 Driver tests: set `--sysroot=""` to support clang with `DEFAULT_SYSROOT`
When testing clang that has been compiled with `-DDEFAULT_SYSROOT` set to some path,
some tests would fail. Override sysroot to be empty string for the tests to succeed
when clang is configured with `DEFAULT_SYSROOT`.

Sergey Dmitriev 4b343fd84c [Clang][OpenMP Offload] Create start/end symbols for the offloading entry table with a help of a linker
Linker automatically provides __start_<section name> and __stop_<section name> symbols to satisfy unresolved references if <section name> is representable as a C identifier (see https://sourceware.org/binutils/docs/ld/Input-Section-Example.html for details). These symbols indicate the start address and end address of the output section respectively. Therefore, renaming OpenMP offload entries section name from ".omp.offloading_entries" to "omp_offloading_entries" to use this feature.

This is the first part of the patch for eliminating OpenMP linker script (please see https://reviews.llvm.org/D64943).

Reid Kleckner e440d23195 Only pass -coverage-notes-file when emitting coverage
The only functional change here is that -coverage-notes-file is not
passed to -cc1 in some situations.

This code appears to be trying to put the gcno and gcda output next to
the final object file, but it's doing that in a really convoluted way
that needs to be re-examined. It looks for -c or -S in the original
command, and then looks at the -o argument if present in order to handle
the -fno-integrated-as case. However, this doesn't work if this is a
link command with multiple inputs. I looked into fixing this, but the
check-profile test suite has a lot of dependencies on this behavior, so
I left it all alone.

Reid Kleckner 01ba7d5efe Un-XFAIL coverage_no_integrated_as.c test on Windows
You can't use -fno-integrated-as for *-msvc triples because no usable
standalone assembler exists. Perhaps we could teach clang to emit a .s
and then reinvoke itself, but that's a bit silly.

Anyway, fix the test by using an Itanium ABI triple, which will become
mingw, which will assume gnu as is a usable assembler.

Heejin Ahn e8b2b8868d [WebAssembly] Add -fwasm-exceptions for wasm EH
Summary:
This adds `-fwasm-exceptions` (in similar fashion with
`-fdwarf-exceptions` or `-fsjlj-exceptions`) that turns on everything
with wasm exception handling from the frontend to the backend.

We currently have `-mexception-handling` in clang frontend, but this is
only about the architecture capability and does not turn on other
necessary options such as the exception model in the backend. (This can
be turned on with `llc -exception-model=wasm`, but llc is not invoked
separately as a command line tool, so this option has to be transferred
from clang.)

Turning on `-fwasm-exceptions` in clang also turns on
`-mexception-handling` if not specified, and will error out if
`-mno-exception-handling` is specified.

Diogo N. Sampaio 73ec745793 [ARM] Take into account -mcpu and -mfpu options while handling 'crypto' feature
Submittin in behalf of krisb (Kristina Bessonova) <ch.bessonova@gmail.com>

Summary:
'+crypto' means '+aes' and '+sha2' for arch >= ARMv8 when they were
not disabled explicitly. But this is correctly handled only in case of
'-march' option, though the feature may also be specified through
the '-mcpu' or '-mfpu' options. In the following example:

  $ clang -mcpu=cortex-a57 -mfpu=crypto-neon-fp-armv8

'aes' and 'sha2' are disabled that is quite unexpected:

  $ clang -cc1 -triple armv8--- -target-cpu cortex-a57
    <...> -target-feature -sha2 -target-feature -aes -target-feature +crypto

This exposed by https://reviews.llvm.org/D63936 that makes
the 'aes' and 'sha2' features disabled by default.

So, while handling the 'crypto' feature we need to take into account:
  - a CPU name, as it provides the information about architecture
    (if no '-march' option specified),
  - features, specified by the '-mcpu' and '-mfpu' options.

a way to disable tests on Windows because they are flaky there. I tried
not to re-enable such tests, but it's possible that I missed some and
this will re-enable flaky tests on Windows. If so, we should disable
them with UNSUPPORTED:system-windows and add a comment that they are
flaky there. So far as I can tell, the lit internal shell is capable of
running all of these tests, and we shouldn't use REQUIRES:shell as a

Android's NDK will start the shared OpenMP runtime in addition to the static

default.  Add this option to enable linking with the static libomp.

Bundler currently requires host triple to be provided no matter if you are performing bundling or unbundling, but for unbundling operation such requirement is too restrictive.

Alexey Bataev 4fb80d56db [Driver][Bundler] Improve bundling of object files.
Summary:
Previously, object files were bundled using partial linking. It resulted
in the following structure of the bundled objects:
```
<host_code>
clang-offload-bundle
__CLANG_OFFLOAD_BUNDLE__<target>
<target_code>
```
But when we tried to unbundle object files, it worked correctly only for
the target objects. The host object remains bundled. It produced a lot of
junk sections in the host object files and in some cases may caused
incorrect linking.

Patch improves bundling of the object files. After this patch the
bundled object looks like this:

```
<host_code>
clang-offload-bundle
__CLANG_OFFLOAD_BUNDLE__<target>
<target_code>
__CLANG_OFFLOAD_BUNDLE__<host>
<host_code>
```

With this structure we are able to unbundle the host object files too so
that after unbundling they are the same as were before.
The host section is bundled twice. The bundled section is used to
unbundle the original host section.

Nico Weber 2346b92f2b clang: Don't warn on unused momit-leaf-frame-pointer when frame pointers are off.
This fixes a regression from r365860: As that commit message
states, there are 3 valid states targeted by the combination of
-f(no-)omit-frame-pointer and -m(no-)omit-leaf-frame-pointer.

After r365860 it's impossible to get from state 10 (omit just
leaf frame pointers) to state 11 (omit all frame pointers)
in a single command line without getting a warning.

This change restores that functionality.

Fixes PR42966.
