Add usage comment to explain how to limit modules in mmm.

68895a96 has introduced the possibility to limit the modules being
built by mmm. In many occasions this can save a lot of developement
time since it allows to build one target without processing all the
makefiles in the Android tree. Unfortunatelly this nice feature is
undocumented. This CL adds the one line documentation.

Try to catch more misuse of $(my-dir).

Amend 64 bit blacklist.

- external/skia now builds on arm64, frameworks/base/libs/hwui
  depends on it.
- external/bluetooth/bluedroid builds on 64 bit, though there
  isn't any obvious way to test it without real hardware.
- frameworks/ml now builds, as does external/srec
- frameworks/opt, frameworks/ex and frameworks/wilhelm don't
  build because of their dependency on frameworks/av.

frameworks/av should probably be dropped out of the blacklist
and replaced by individual markers on targets that we want
for 64 bit (we don't want all of them for arm64).

Use analyzer at new location: prebuilts/misc/{linux-x86,darwin-x86}/analyzer

Analyzer needed by WITH_STATIC_ANALYZER and WITH_SYNTAX_CHECK is
moved from prebuilts/clang/{linux-x86,darwin-x86}/host/3.3 to
prebuilts/misc/{linux-x86,darwin-x86}/analyzer

See https://android-review.googlesource.com/#/c/83852/

BUG=13243591

Usage:

"WITH_SYNTAX_CHECK=1 make ..." instructs build system to invoke "clang -fsyntax-only"
to utilize clang's better diagnostics before calling LOCAL_CC/LOCAL_CXX for code generation.
The compilation time is slightly longer, and the generated object file should be the same as
w/o WITH_SYNTAX_CHECK

"WITH_STATIC_ANALYZER=1 m/mm/mmm/mma/mmma ..." instructs build system to run static
analyzer via "clang --analyze" on a successful build.  If analyzer finds any issue, instruction
to open report is displayed. See http://clang-analyzer.llvm.org/scan-build.html for details.

WITH_STATIC_ANALYZER trumps WITH_SYNTAX_CHECK if both exist.  Project use lots of GCC extensions
(eg. nested function) not supported by clang may opt out by adding LOCAL_NO_STATIC_ANALYZER:=true

Extend YACC and LEX handling to .yy and .ll files.

The external mclinker project has .yy and .ll files that
require the same rules as .y and .l.

Do not remove the generated .hpp file from yacc.

Depending on the file extension of the generated C++ file,
bison will generate a #include of a .h or .hpp. So both files
must be kept in the generated directory.
