* [linker] Optimize calls to BlockLiteral.SetupBlock to inject the block signature.
Optimize calls to BlockLiteral.SetupBlock[Unsafe] to calculate the block
signature at build time, and inject it into the call site.
This makes block invocations 10-15x faster (I've added tests that asserts at
least an 8x increase).
It's also required in order to be able to remove the dynamic registrar code in
the future (since calculating the block signature at runtime requires the
dynamic registrar).
* [mtouch/mmp] Add support for reporting errors/warnings that point to the code line causing the error/warning.
Add support for reporting errors/warnings that point to the code line causing
the error/warning by adding ErrorHelper overloads that take the exact
instruction to report (previously we defaulted to the first line/instruction
in a method).
* [tests] Add support for asserting filename/linenumber in warning messages.
* Make all methods that manually create BlockLiterals optimizable.
* [tests] Create a BaseOptimizeGeneratedCodeTest test that's included in both XI's and XM's link all test.
* [tests] Add link all test (for both XI and XM) to test the BlockLiteral.SetupBlock optimization.
* [tests] Add mtouch/mmp tests for the BlockLiteral.SetupBlock optimization.
* [tests][linker] Make the base test class abstract, so tests in the base class aren't executed twice.
* [tests][linker] Don't execute linkall-only tests in linksdk.
The optimization tests only apply when the test assembly is linked, and that
only happens in linkall, so exclude those tests in linksdk.
* [tests][mmptest] Update test according to mmp changes.

* [docs] mmp shows MM errors/warnings.
* [docs] Improve according to reviews.
* [tests] Fix merge failure causing test duplication.
* [tests] Build the native test library for macOS and create a binding project for it.
Also add the new binding project to the xammac and link all XM test projects,
which allows us to stop excluding tests that require the native library and
the corresponding bindings.
* [tests] Include more tests in xammac_tests.
* [tests] Correctly ignore the ObjC exception tests in release mode.
monotouch-test has a wildcard to automatically include new test files, but
this should not include generated files, because:
* The generated files are generated when needed, which means we can't rely on
the wildcard to trigger their generation, because the wildcard won't find
them before they exist, and as such msbuild won't detect that they're
needed.
* This means the generated files must be listed separately, but in that case
they shouldn't be found by the wildcard too, because that leads to:
/Library/Frameworks/Mono.framework/Versions/5.4.0/lib/mono/msbuild/15.0/bin/Roslyn/Microsoft.CSharp.Core.targets(84,5): error MSB3105: The item "ObjCRuntime/TrampolineTest.generated.cs" was specified more than once in the "Sources" parameter. Duplicate items are not supported by the "Sources" parameter.
So move the generated files to a different directory, so that the wildcard
doesn't find them.
The native linker treats object files (.o) and static libraries (.a files,
which are archives of .o files) differently.
The native linker will always include object files into the executable:
$ echo "void xxx () {}" > foo.m
$ clang -c foo.m -o foo.o -arch x86_64
$ ld foo.o -dylib -o foo.dylib -macosx_version_min 10.12 -arch x86_64
$ nm foo.dylib
0000000000000fe0 T _xxx
However, if the object file is inside a static library:
$ echo "void xxx () {}" > foo.m
$ clang -c foo.m -o foo.o -arch x86_64
$ ar cru foo.a foo.o
$ ld foo.a -dylib -o foo.dylib -macosx_version_min 10.12 -arch x86_64
$ nm foo.dylib
<no output>
This means that our testing library (libtest.a) which is a fat library of
_object files_, do not show the problems reported in bug #51548.
So:
a) I've fixed the creation of libtest.a to be a fat library of _static
libraries_. This causes the `FastDev_LinkWithTest` test to fail exactly
like in bug #51548.
b) I've made mtouch pass `-u <native symbol>` to the native linker, for every
native symbol referenced in a managed assembly, when creating a dylib.
Amazingly this seems to work fine even with symbols to Objective-C classes
(`_OBJC_CLASS_$_<class name>`).
c) This also required adding support for collecting the Objective-C names of
all managed types registered with Objective-C to the linker. The
information is already available in the static registrar, but that would
require us to make sure the static registrar is executed before compiling
dylibs, which means those two tasks won't be able to run in parallel (also
there's no guarantee we'll even run the static registrar).

Generate trampoline and registrar tests that tests if a return type requires objc_msgSend or objc_msgSend_stret.
Now it's much easier to test new return types (a single line of code), which
avoids a _lot_ of copy-pasting, and makes sure all the different variations
are tested properly.
These new tests found several bugs, which are fixed in subsequent commits.
