Create a <LANG>_COMPILER_LAUNCHER target property (initialized by a
CMAKE_<LANG>_COMPILER_LAUNCHER variable) to specify a compiler launcher
tool. This will supersede the CMAKE_<LANG>_COMPILER_ARG1 approach to
using such tools. The old approach set CMAKE_<LANG>_COMPILER to the
launcher tool while the new approach leaves this variable set to the
actual compiler.
Implement this property for Makefile and Ninja generators. It cannot be
implemented for VS or Xcode generators as the IDE build tools offer no
such hooks.
The chaining logic doesn't belong to the container, and the
CMakeInstance pointer doesn't need to be in cmPropertyMap.

Add CROSSCOMPILING_EMULATOR target property for executables. This is used by
subsequent patches to run exectuables created for the target system when
crosscompiling. The property is initialized by the
CMAKE_CROSSCOMPILING_EMULATOR variable when defined.

Pre-C++98 compilers required that the template argument be
used in the function parameters. Those compilers are no longer
supported as hosts, so drop the workaround.

Commit v3.1.0-rc1~297^2~5 (cmTarget: Drop 'head' argument from
GetSourceFiles, 2014-07-10) exposed a dormant bug in source file computation,
causing the test case to regress. After that commit, the source file
computation and caching finds an existing container of source files. Prior to
that patch, the GetSourceFiles method was called with either a null pointer
for the head cmTarget, or it was called with the this pointer. The
processSources method is eventually called, which normalizes the difference
between the null pointer and the this pointer for the head target. However,
the cache key depends on the actual pre-normalized pointer. The change in
that commit caused the entry to be found in the cache where it was not before,
which resulted in incorrect behavior.
Prior to that commit, the test case also fails if the GetSourceFiles overload
taking a vector<cmSourceFile*> is changed to normalize the head target at
the beginning of the method:
cmTarget const* head = head_ ? head_ : this;
Such a construct was correctly used in other locations where similar caching
was in place, before being removed in commit v3.1.0-rc1~310^2~25 (cmTarget:
Remove 'head' argument from GetLinkInformation, 2014-06-12), but is not
neccessary anymore.
Commit v3.1.0-rc1~674^2~2 (cmTarget: Cache the cmSourceFiles in
GetSourceFiles., 2014-04-05) introduced the caching, but fails the test case
for an unrelated reason. That unrelated error was introduced in
commit v3.1.0-rc1~688^2~5 (cmTarget: Allow any generator expression in
SOURCES property., 2014-03-18) and fixed in
commit v3.1.0-rc1~561^2~1 (cmTarget: Fix listing of source files at
configure-time., 2014-04-13).
All commits which fail the test case in the testable way do so when such a
cached version of the source files is found and returned at generate
time. In the test case, the cached content is populated at configure-time
through the use of the deprecated LOCATION property with CMP0026 OLD. The
cached content is an empty container for the bar target in the test case,
because its source file 'foo.cpp.o' is not known until generate-time. That
means that no source files are available to compute the link language and
the reported error is issued.
The actual problem is that the SourceFilesMap should be cleared after
configure time by cmTarget::ClearLinkMaps. Clear it there now.
55a73e6b Use the cmJoin algorithm where possible.
