Add SharedEnvExtension#gcc_with_cxx11_support? to centralise the
logic for checking whether a compiler is known to support C++11.
Update logic to accept GCC 4.8 and above (including 6). Thereby also
address oversight in #163 where support for GCC 6 was added without
updating the C++11 compiler whitelist.
Add tests for Superenv#cxx11.
Closes#346.
Old logic doesn't include revision. This fixes that, and passes the
whole formula prefix path to avoid duplicating the path-construction
logic.
Closes#80.

Previously, superenv did not try to filter -I or -L flags
based on the list of requested dependencies; as a result, buildsystems
which opportunistically discover Homebrew-installed libraries were able
to link against them even under superenv.
This adds a list of all requested dependencies to the superenv environment,
and compares all -I and -L flags against those; any Cellar and opt paths
found which resolve to unrequested dependencies are filtered out.
SDK 10.10 isn't something that exists for Xcode 7, so stop looking for
it and rely on MACOSX_DEPLOYMENT_TARGET instead.

`Library/ENV` like `Library/Homebrew` is part of Homebrew basecode. It
should be able to be accessed during the `brew tests`.
By adding HOMEBREW_ENV_PATH variable, we allow test suit to locate these
codes.
HOMEBREW_MAKE_JOBS can be a multidigit number. The regex should match
the entire number not just the last digit.

add guard in Formula#file_modified? to prevent git popup
add guard in Superenv.bin before calling MacOS::Xcode.version
add guard against missing Xcode/CLT in Xcode.uncached_version
return nil instread of 0 in uncached_version when Xcode/CLT are not present, to distinguish from linuxbrew behavior
checks against pour_bottle? and needs_relocation?, add guard around keg.relocate_install_names to check pour_bottle?/needs_relocation? as well
needs_relocation? becomes skip_relocation?, use cellar attr to indicate relocation instead of does_not_need_relocation
MacOS.can_build? becomes MacOS.has_apple_developer_tools?
It's not clear whether it returns MAKEFLAGS with or without -j<n>, and
neither is particularly useful behavior, given you can easily get the
exact value by calling ENV["MAKEFLAGS"]. So let's not commit to this
API.
The xcrun script should be skipping the ENV directory when it scans
$PATH looking for tools to run. Unfortunately, the script compares the
paths found to the real path of the ENV directory (following symlinks),
but superenv was adding the nominal path to $PATH, not following
symlinks. As a consequence, platforms with Xcode < 4.3 would get into
infinite loops when trying to call non-system versions of gcc, as xcrun
calls the ENV version of gcc-X.X which calls xcrun and so on forever.
This commit changes superenv to follow symlinks when determining the bin
path to use.

I found the dual use of CMAKE_*_PATH variables to make it difficult to
reason about this code. Now a separate set of variables are used to
communicate with the cc wrapper, and less work is performed in the
wrapper itself.
We no longer pass the SDK include path as a -isystem directory on
Xcode-only setups. Doing so is redundant with `--sysroot` and has other
side effects, namely changing the include path search order, which can
break compilation of some software (e.g. qemu).
On Xcode-only 10.9, we can additionally omit `--sysroot`, as the correct
paths are built into the tools.
A new variable, HOMEBREW_SYSROOT, is used to this information to the
wrapper. It will be unset on Xcode-only 10.9. HOMEBREW_SDKROOT will
continue to be set, as it is used for other things besides setting the
include search path.
