Move all the flags that are used everywhere (or should be used
everywhere) into cc/config/global.go:
-no-canonical-prefixes
-fno-exceptions
-Wno-multichar
-O2
-g
-fno-strict-aliasing
Also remove flags that are already in noOverrideGlobalCflags:
-Werror=pointer-to-int-cast
-Werror=int-to-pointer-cast
x86 and x86_64 were specifying -fstrict-aliasing, but that was
being overriden later by -fno-strict-aliasing, so remove it.
ARM devices still override -fno-strict-aliasing to -fstrict-aliasing
when using ARM (vs. Thumb) instruction set.

Enabling the lto property for a module builds that module and all static
dependencies with LTO.
LTO (link-time optimization) allows the compiler to optimize and
generate code for the entire module at link time, rather than
per-compilation unit. LTO is required for Clang CFI and other
whole-program optimization techniques. LTO also allows cross-compilation
unit optimizations that should result in faster and smaller code, at the
expense of additional compilation time.
Test: make -j12 libc with lto: true for libc

Clang supports specific CPU targeting and optimization
for Kryo.
This switches us to using the specific Kryo targeting
when Clang is used. For other compilers, we fallback
to cortex-a57 targeting.
Also, move the replaceFirst function to a shared location.

Shared libraries are now installed to different directories depending on
their types.
* NDK libraries: /system/lib/ndk
* VNDK libraries: /system/lib/vndk
* VNDK-ext libraries: /system/lib/vndk-ext
* Framework-only libraries: /system/lib
* Vendor-only libraries: /vendor/lib
* Same-process HALs: /vendor/lib/sameprocess
In addition, a new module type vndk_ext_library is added. It is almost
identical to cc_shared_library but it introduces another attribute
'extends'. This is use to reference the vndk library that this vndk-ext
library is extending.
For example, in order to extend a vndk library libFoo:
cc_library {
name: "libFoo",
srcs: [...]
}
---------------------
vndk_ext_library {
name: "libFoo-extended",
srcs: [...]
extends: "libFoo"
}
Then, libFoo will be installed as /system/lib/vndk/libFoo.so and
libFoo-extended will be installed as /system/lib/vndk-ext/libFoo.so.
Note that file name of the latter is libFoo.so, not libFoo-extended.so:
file name of an extending module is automatically set to that of the
extended module.

Export a list of libraries in the VNDK, which is currently empty.
Take in Make's global BOARD_VNDK_VERSION, and use that as the SDK
version for modules that specify use_vndk: true.
Modules that use the vndk have some configuration as if they were
building against the NDK (the absence of globally defined headers), but
in other cases look like platform modules (using the platform libc++,
for now).
This change does not attempt to enforce any linking constraints, that
will come in a later patch.

As I have been updating to LLVM ~4.0, there are numerous locations where
3.8 is hard-coded, and unable to be overridden. This change adds a new
function for getting the ClangShortVersion(), which can look at
environment variables that override this value (particularly useful for
two-stage compilation, where version numbers change between builds).
