Switch to use RSCompilerDriver.
This commit is large. It does:
1. Clean-up RSScript. ScriptCached and ScriptCompiled are removed.
2. Switch to use CompilerConfig.
3. Switch to use RSInfo. MCCacheReader and MCCacheWriter are removed.
4. Update C API implementation of libbcc (i.e., bcc.cpp). Note that
it'll be completely removed once there's no clients relying on it.

Introduce RSInfo and its reader/extractor/writer.
This commit only adds files that implements RSInfo class and DOES
NOT switch to use it.
RSInfo defines the new file format to cache the metadata and
RS-specific information from the source bitcode.
It's the replacement of the old "MC cache" whose name is ambiguous
and some fields within that are deprecated after legacy JIT was
removed.
Reader of RSInfo reads information from the file we called "RS info
file." It will replace MCCacheReader.
Extractor of RSInfo extracts information from the metadata section of
the source bitcode. It will replace MetadataExtractor.
Writer of RSInfo serializes a RSInfo object to a file such that
we can load it quickly using RSInfo reader later. It will replace
MCCacheWriter.
RSInfo unifies the interfaces to get the RS-specific information
such as #rs_export_var supplied by the developers either from file
(RS info file) or from the source bitcode. Later commit will prove
that.
RSInfo uses signature ("\0rsinfo\n") which is different from the
old MC cache ("\0bcc").
The version (MCO_VERSION in bcc_mccache.h) is increased by 1 in this
commit since we remove res_type in MCO_Dependency. RSInfo inherits
the version number comes from old MC cache therefore its version
number starts with 3.

Introduce SymbolResolver and its subclasses.
SymbolResolver provides a clean way to do the symbol lookup at
runtime.
LookupFunctionSymbolResolver searches a symbol through a given
function with context supplied.
BCCRuntimeSymbolResolver searches symbol from a predefined symbol-to-
address array which replaces the FindRuntime() function defined in
Runtime.c previously.
SymbolResolverProxy chains the SymbolResolvers and searches the symbol
one by one following the chain until it founds the definition of the
symbol.

Introduce InputFile/OutputFile and FileMutex.
FileHandle is replaced with InputFile/OutputFile and FileMutex.
Use InputFile when you want to open a file in read-only.
USe OutputFile when you open a file for writing.
Both of them provide a reliable way to access the files and perform
the I/O operations.
Given a name "foo", FileMutex creates a file named "foo.lock" and
tries to acquire an advisory lock (flock) on this file.
FileHandle, which uses the file it's openning for locking, may corrupt
the file contents when two or more processes are trying to gain the
lock for reading/writing. For example:
Process #2 creates foo
Process #1 opens foo
Process #2 opens foo
Process #2 locks foo (exclusively) (success)
Process #1 locks foo (failed, retry #1)
Process #2 starts writing foo
Process #1 opens and truncates foo (note there’s O_TRUNC in the flag)
Process #2 writes foo continually (foo is corrupted from now on ...)
Process #1 locks foo (failed, retry #2)
...
Process #1 locks foo (reach the max retries and return)
Process #2 gets done on writing foo (foo is corrupted ...)
Process #2 unlocks and closes foo (foo is corrupted)

Fix (GDB) debugging of code loaded from cache
When loading code from cache, set ELF section headers to point to real
location of executable code. This fixes GDB errors about being unable to
insert breakpoints at an invalid address.

Remove USE_CACHE support, since we only need MC support.
BUG=6051742
This change also removes the legacy bcc_cache.h header by moving any relevant
defines still there to bcc_mccache.h. These types/values are now renamed to
generally use "MCO" instead of "OBCC".

BUG=6051742
This also removes references to MCJIT, since we use MC CodeGen, and not the
actual LLVM MCJIT path.

Enable debugging of RS code under GDB
- Add/integrate GDBJITRegistrar support class for interfacing with GDB
-- Once the GDBJITRegistrar is merged into LLVM trunk (and AOSP upgrades LLVM)
all files GDB* should be removed, and replaced with appropriate includes
- Basic [host|target]-side integration tests
-- host-tests: use bcc driver and clang to verify gdb output
-- target-tests: run skeleton apk on target and verify gdb output
- Add support for optimization_level metadata in bcinfo, libbcc
-- Disabled some LTO passes when optimization_level = 0
-- move register allocator registration after metadata inspection
- Initial version of android-commands.py GDB plugin (for test infrastructure)
-- relevant commands: load-android-app, run-android-app, start-android-app
-- tested versions: gdb (7.2, 7.3), python (2.6, 2.7)
- build 'bcc' driver tool by default in eng builds
