[interp] Error handling refactor (optimize non-exception path) (helps clang save stack) (mono/mono#16371)

While working on stack reduction, I believe I found that
the compiler could not tell how THROW_EX and/or NULL_CHECK terminate.

That is, essentially, the success paths preserve volatile registers.
They do not have to be spilled/filled.
This tweak should make it clearer to the compiler, optimized common paths, and not slow down uncommon paths.

This also cleans it up a little and reduces macro expansion, and then possibly should allow for reinlining what is now used only once.

Also add some const so it can be casted away less.

Believed to save 32 bytes of stack with Linux/amd64/clang, nothing for gcc.
And a nice cleanup.

Fix special case tramp assert in x86/amd64. (mono/mono#16476)

https://github.com/mono/mono/pull/16408 temporary fixed a tramp issue on
x86 (also exist on amd64). This commit fixes the underlying issue and re-enable
the use of noreturn outside of netcore.

The problem hit by the use of OP_NOT_REACHED on x86/amd64 is due to a specific
case when the address to patch happens to fall at the start of a different
managed method. Since the use of OP_NOT_REACHED can end a method
with the call instruction on x86/amd64 in combination with how patch location
(using the return address from stack) is resolved, the implementation in
mono_arch_patch_callsite didn't take this case into account, reading incorrect
patch data, triggering assert oh x86. So, based on timing we could end up with
the following code:

025715B3 call 02570D98
025715B8 push ebp

since the patch target is 025715B8, but also the start of a completely different
method, method_start == origin_code. The fix is to detect this case on x86/amd64
(done on each arch since the way origin_code is detected is arch specific)
and then use a method_start of NULL, that is already a supported scenario.

```

This causes the mono_valloc() function to try to use the MAP_32BIT flag for mmap().

However as mentioned in the comment for the symbol in mman.h it seems to require a special entitlement
which isn't available/documented anywhere yet.
This in turn causes the mmap call to fail presumably because we're missing that entitlement.

Instead we now skip setting this flag on Apple platforms to make mmap() behave like it did before.

be on a sort of critical path to reduce frame size.

These registers can be encountered in the unwind info for functions with a cold

Aleksey Kliger (λgeek) [Thu, 22 Aug 2019 14:10:09 +0000 (10:10 -0400)]
[android] mono_dl_open_file: use g_file_test only on absolute paths (mono/mono#16387)

The intention of calling `g_file_test (file, G_FILE_TEST_EXISTS)` where file is
the name of a shared library we want to open is to speed up probing for
non-existent libraries.

See https://github.com/mono/mono/pull/12074

The problem is that if file is just a simple "libdl.so" then `dlopen (file)`
doesn't just look for it in the current working directory, it will probe some
other paths too.  (For example on desktop linux you'd also look in all the
directories in LD_LIBRARY_PATH).  So the g_file_test() call is not a robust way
to avoid calling dlopen if the filename is relative.

But it actually broke more things: https://github.com/xamarin/xamarin-android/issues/3388

When probing for "libdl.so" on Android mono_lookup_pinvoke_call will first try
prepending some paths that it knows about and we end up calling
`dlopen ("/system/lib/libdl.so")` which will fail because Bionic has security
restrictions on what code can dlopen something from /system/lib with an
absolute path.  Eventually mono_lookup_pinvoke_call will go back to trying the
bare "libdl.so" which hits `g_file_test` and returns NULL.

The new code only does the file test if we pass it an absolute path, which
gives Bionic's dlopen a chance to deal with relative paths however it needs to.

[profiler] Rename helper functions to have common prefix

Unfortunately https://github.com/mono/mono/pull/16335 didn't fix the new symbols showing up in the log profiler module.
The reason is that we actually pass `--disable-visibility-hidden` for iOS builds in https://github.com/mono/mono/blob/mono/mono@0b6d95e8ce7c882e2db9e89fa0dec850c687f65e/sdks/builds/ios.mk#L98.

Rename the helper functions instead to have a common prefix so they can be ignored in xamarin-macios tests.

[interp] Outline box_nullable. (mono/mono#16356)

Without being entirely scientific about it, this case seems
to be one that uses more than typical locals and therefore
be on a sort of critical path to reduce frame size.

I have a change that reduces frame to 0x78 bytes (albeit
not yet working) and to achieve that, in this case I refetched
the locals after function calls.

This achieves similar but perhaps more elegantly.
If we rest at larger frame size then this case might not be on the critical path.

thread names: coop, constants, usually ignore-error. (mono/mono#16272)

- Convert setting thread name to be coop-compatible.

- For constant thread names, just retain the constant, not a copy.
  This includes producing and using constant unicode thread names on Windows.

- Make setting a thread name often non-fatal, except where mandated by public API.

- From earlier PR: mono_free (mono-publib.c) would no longer be referenced and therefore
  no longer exported. That broke profilers and maybe other externals.
  Choices:
     1 Use it instead of g_free randomly sometimes.
     2 Call it randomly sometimes.
     3 include it in external-only.c or object.c
     4 Mark it external only (breaks profiler).
     5 Use a .def file or Unix equivalent.

     5 is best, 2 is done here, the advantages/disadvantages
     among most choices are subtle. 3 is probably better than 2
     but is slightly bigger change, to put off -- you'd stop
     compiling mono-publib.c and move it to include/extra_redist.

     The advantage of not-.def file is perhaps that it is exposed
     by the compiler, so maybe easy to port and work with.
     People are more comfortable with obscure C extensions than
     any linker options, and there are multiple linkers to contend
     with. Arguably there are fewer compilers.
