Since these are primarily useful for deeply embedded targets where code size is
very important, they are each in a separate file making use of infrastructure
in sync-ops.h. This allows a linker to include just the functions that are
actually used.

Patch by Viktor Kutuzov!

Patch by Brad King.

Our add_sanitizer_rt_symbols macro reads the LOCATION property of a
library to compute the location of the "lib<name>.a.syms" file to
generate next to the corresponding "lib<name>.a" library file.  CMake
3.0 introduces policy CMP0026 to disallow reading of the LOCATION target
property from non-imported targets in favor of the more powerful
$<TARGET_FILE> generator expression.

Teach add_sanitizer_rt_symbols to use the $<TARGET_FILE> generator
expression to compute the location of the symbols file to generate
with a custom command.  CMake 3.0 also adds support for generator
expressions to install(FILES) so use it when available to simplify
installation of the symbols file of the proper configuration.

Patch by Brad King.

When using a multi-config generator with CMake, such as for VS or Xcode,
the LOCATION target property value contains a placeholder such as
"$(Configuration)" that is meant for substitution by the native build
tool. The install(FILES) command does not understand this name and will
not install the symbols file correctly when using these generators.

Teach add_sanitizer_rt_symbols to read the more-specific target property
LOCATION_<CONFIG> that has a per-configuration value and no placeholder.
On single-configuration generators (Makefile, Ninja), CMAKE_BUILD_TYPE
contains the name of the one configuration to be built.  On multi-config
generators (VS, Xcode), CMAKE_CONFIGURATION_TYPES contains the list of
possible configurations.  In the latter case, loop over the configs and
add a configuration-specific install(FILES) rule for each one.

Place the code block inside an if(TRUE) block so it can be made
conditional in a following change without updating indentation.
