Recent changes canonicalized clang_rt library names to refer to
"i386" on all x86 targets. Android historically uses i686.
This change adds a special case to keep i686 in all clang_rt
libraries when targeting Android.

CMake's add_custom_target is considered to be *always* out of date.
This patch changes it to a combination of add_custom_target and
add_custom_command which actually tracks dependencies' timestamps.
On my machine this reliably saves 6-7 seconds on each test group.
This can be a large difference when debugging small tests.

into a function.
Most CMake configuration under compiler-rt/lib/*/tests have
almost-the-same-but-not-quite functions of the form add_X_[unit]tests
for compiling and running the tests.
Much of the logic is duplicated with minor variations across different
sub-folders.
This can harm productivity for multiple reasons:
For newcomers, resulting CMake files are very large, hard to understand,
and hide the intention of the code.
Changes for enabling certain architectures end up being unnecessarily
large, as they get duplicated across multiple folders.
Adding new sub-projects requires more effort than it should, as a
developer has to again copy-n-paste the configuration, and it's not even
clear from which sub-project it should be copy-n-pasted.
With this change the logic of compile-and-generate-a-set-of-tests is
extracted into a function, which hopefully makes writing and reading
CMake much easier.

This patch addresses two issues:
Most of the time, hacks with `if/else` in order to get support for
multi-configuration builds are superfluous.
The variable `CMAKE_CFG_INTDIR` was created precisely for this purpose: it
expands to `.` on all single-configuration builds, and to a configuration
name otherwise.
The `if/else` hacks for the library name generation should also not be
done, as CMake has `TARGET_FILE` generator expression precisely for this
purpose, as it expands to the exact filename of the resulting target.

Summary: Currently, we build the compiler-rt runtimes with link-time optimization if LTO is configured for the LLVM project. This will break external programs that don't invoke the linker in such a way that it supports LLVM's LTO. To avoid this, this change causes the compiler-rt runtimes to be compiled with -fno-lto. This also makes the check-profile tests work on systems when doing a lld LTO build on a system where the system linker does not support LLVM LTO.

The build system was inconsistent in its naming conventions for
link flags. This patch changes all uses of LINKFLAGS to LINK_FLAGS,
for consistency with cmake's LINK_FLAGS property.
This patch should make it easier to search the source code for
uses of link flags, as well as providing the benefit of improved
style and consistency.

This patch builds on LLVM r279776.
In this patch I've done some cleanup and abstracted three common steps runtime components have in their CMakeLists files, and added a fourth.
The three steps I abstract are:
(1) Add a top-level target (i.e asan, msan, ...)
(2) Set the target properties for sorting files in IDE generators
(3) Make the compiler-rt target depend on the top-level target
The new step is to check if a command named "runtime_register_component" is defined, and to call it with the component name.
The runtime_register_component command is defined in llvm/runtimes/CMakeLists.txt, and presently just adds the component to a list of sub-components, which later gets used to generate target mappings.
With this patch a new workflow for runtimes builds is supported. The new workflow when building runtimes from the LLVM runtimes directory is:
> cmake [...]
> ninja runtimes-configure
> ninja asan
The "runtimes-configure" target builds all the dependencies for configuring the runtimes projects, and runs CMake on the runtimes projects. Running the runtimes CMake generates a list of targets to bind into the top-level CMake so subsequent build invocations will have access to some of Compiler-RT's targets through the top-level build.
Note: This patch does exclude some top-level targets from compiler-rt libraries because they either don't install files (sanitizer_common), or don't have a cooresponding `check` target (stats).
llvm-svn: 279863
This is a wrapper target of all the component install targets. This wrapper target will be used by the new LLVM runtimes directory to connect top-level targets to the runtime project target.

Summary:
This patch is a refactoring of the way cmake 'targets' are grouped.
It won't affect non-UI cmake-generators.
Clang/LLVM are using a structured way to group targets which ease
navigation through Visual Studio UI. The Compiler-RT projects
differ from the way Clang/LLVM are grouping targets.
This patch doesn't contain behavior changes.

Summary:
When using a multi-configuration build (i.e. MSVC) the output path where
libraries are dropped is incorrect.
Example:
```
C:\src\llvm\examples>d:\src\llvm\build\Release\bin\clang-cl.exe -fsanitize=address test.cc
LINK : fatal error LNK1181: cannot open input file 'd:\src\llvm\build\Release\bin\..\lib\clang\3.9.0\lib\windows\clang_rt.asan-i386.lib'
```
The dropped executable path contains the configuration 'Release':
```
'd:\src\llvm\build\Release\bin\..\lib\clang\3.9.0\lib\windows\Release\clang_rt.asan-i386.lib'
```
The variable 'RUNTIME_OUTPUT_DIRECTORY' is used to specify the output directory.
But CMAKE is appending the current configuration (i.e. Debug, Release).
see: https://cmake.org/cmake/help/v3.0/prop_tgt/RUNTIME_OUTPUT_DIRECTORY.html
```
"Multi-configuration generators (VS, Xcode) append a per-configuration subdirectory to the specified directory."
```
To avoid this problem, the configuration specific variable must be set:
'RUNTIME_OUTPUT_DIRECTORY_DEBUG', 'RUNTIME_OUTPUT_DIRECTORY_RELEASE', and so on.
