08cca28f92 Add support for ubsan. 
Rather than adding LOCAL_UB_SANITIZER, LOCAL_THREAD_SANITIZER, etc for
each new sanitizer, deprecate LOCAL_ADDRESS_SANITIZER in favor of
LOCAL_SANITZE that mirrors the behavior of -fsanitize=<sanitizers>.

For example, the following will use both asan and ubsan:

    LOCAL_SANITIZE := address undefined

We'll leave LOCAL_ADDRESS_SANITIZER around for compatibility until we
can clean up the tree.

b58fb4aac6 Let clang decide ASan linker flags for the host. 
Pass -fsanitize=address instead of manually specifying asan libraries
and other linker flags.

Note that we enable LOCAL_ALLOW_UNDEFINED_SYMBOLS by default for host
builds because ASAN only links symbols in the final executable, so
there will _always_ be undefined symbols in intermediate libraries.

433f1614b0 Switch to Clang 3.6. 
This change also defaults C compilations with clang to gnu99, and turns off
the -Winconsistent-missing-override flag, since we need further cleanup to
turn it on. -finline-functions is an unnecessary flag that only gcc needs.

1568029218 Add more support for GLOBAL_CONLYFLAGS. 
This will be necessary to support -std=gnu99 mode for clang 3.6, which
defaults to C11 mode (unlike prior releases that use C99).

c141b85ef1 Use automatic color option with the latest clang. 
Bug: 18187181

Now that I checked in the latest prebuilts, clang will automatically use
color on terminals and no color on redirection to files or non-terminals.

Ying Wang
24e03369cf Add -Wno-unused-command-line-argument to clang cflags to enable ccache. 
Previously ccache is disabled when it fails calling clang's preprocessor with
unused arguments (such as '-Wa,--noexecstack') in the command line.

See http://petereisentraut.blogspot.com/2011/05/ccache-and-clang.html.
(-Qunused-arguments suppresses more than
-Wno-unused-command-line-argument does.)

8affa161fe Use new variable LLVM_PREBUILTS_VERSION to simplify path construction. 
This removes the hard-coded '3.5' in the various paths and makes switching to
a new toolchain easier from the command line (m LLVM_PREBUILTS_VERSION=3.6).
