Revert "Revert "Write dex files to oat file early.""
This reverts commit 919f5536182890d2e03f59b961acf8f7c836ff61.
Fix linker error (Mac build):
Replace inline definition of art::ZipArchive::~ZipArchive()
with an out-of-line definition in zip_archive.cc to avoid
direct reference to CloseArchive() from libart-compiler due
to inlining. Note that libart is linked against -lziparchive
but libart-compiler is not.

Write dex files to oat file early.
Write dex files to oat file before we actually open and
verify them. Instead, open and verify the copies from the
oat file and use these. This way, in the most common case
of zipped dex files, we have mmapped dex files instead of
inflated dex files. That reduces the number of dirty pages
used by dex2oat.
Reading /proc/self/statm after we write the oat file for
a compilation of a certain large app on Nexus 5 AOSP build
with -j1, three attempts before and after this CL gave
before: 346061 189462 6269 26 0 140723 0
346189 189450 6269 26 0 140851 0
346061 189463 6269 26 0 140723 0
after: 346186 185808 23040 27 0 140468 0
346186 185819 23040 27 0 140468 0
346186 185822 23040 27 0 140468 0
These values are in pages (4KiB), so while the "size"
(=VmSize) is essentially unchanged, the "resident" (=VmRSS)
is over 14MiB less and the "shared" (i.e. backed by a file)
is 65.5MiB more. That is, the amount of dirty non-pageable
memory used is reduced by about 80MiB.
The oat file format has changed slightly, the class offset
table has been moved from the OatDexFile to its own section.
This actually fixes the alignment of these offsets as they
could have been unaligned previously, yet accessed as normal
with significant performance impact if the kernel has to
emulate the unaligned access (say, mips).

art: Refactor RuntimeOptions/ParsedOptions
Refactor the RuntimeOptions to be a
type-safe map (VariantMap, see runtime_options.h) and the ParsedOptions
to delegate the parsing to CmdlineParser (see cmdline/cmdline_parser.h).
This is the start of a command line parsing refactor, and may include
more in the future (dex2oat, patchoat, etc).
For more details of the command line parsing generator usage see cmdline/README.md
