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.

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.

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

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.

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.)

For mips target, gcc passes -KPIC to assembler by default,
but clang passes -KPIC only if -fPIC or -fpic is given.

These aren't needed now that we only use the compiler/headers that exist in
the prebuilts/clang directory.

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).

Bug: 17333374
Add RS_TRIPLE_CFLAGS to ensure that we build with the proper defines on
targets like x86. This also changes all build targets to use the
proper 32/64-bit triples when creating their runtime libraries.

Add mips64r6 target and corresponding mips32r6 target.
Defaults remain as mips64r2 and mips32r2.
Apply -FP64A codegen subsetting to mips32r6 only.
Access FR=0 odd-numbered 32-bit float regs only via
double-prec even-numbered regs, not by single-prec ops.

Use 4.9 mips64el toolchain for both 64- and 32-bit builds.
Tell ld when 32-bit links are required.
Override 4.9's changed defaults for mips floating point
register use, to get same assembler rules as 4.8 and earlier.
Also: drop unused soft-fp build targets, cleanout redundant
compiler options, and remove extraneous Android.mk file.
