This is a preparation CL to enable actually sharing JIT'ed code between
isolates within the same isolate group.
We start with conservative settings, disabling various compiler
optimisations. We will lift those restrictions step-by-step.
Since this is guarded by FLAG_enable_isolate_groups it will not affect
any production code. Only individual tests which opt-in via the flag.
TEST=Existing tests opt'ing into --enable-isolate-groups.

It relies on flutter copy of clang distribution, same one that is used to build flutter/engine.
It addressed several deprecated warnings from clang compiler for functions like strdup, unlink, etc.
It allows few warnings still since they are triggered in third_party sources.

When these were originally added, we thought we would be able to use them in place of ifdefs and rely on the compiler optimizations and linker GC to remove things. This turned out not to reliably remove what we wanted removed, so we ended up with the ifdefs anyway.

This CL enables passing --disassemble to e.g. a product mode gen_snapshot
which used to not have the flag even when the disasm. was forcefully
included.
This CL also:
- Fixes numerous typos: marco -> macro.
- Reorders the _four_ types of flags in order of strictness.

Passes bodies are moved into compiler_pass{.cc,.h}.
Invoking a pass is just INVOKE_PASS(Name) now, instead of putting a bunch of
if-s and calls in compiler.cc or precompiler.cc.
We also consolidate ability to print IL and enable-disable passes under a
single flag --compiler-passes, e.g.
--compiler-passes=-Inlining,-CSE disable inlining and CSE passes
--compiler-passes=Inlining+ print IL after Inlining pass and all
subsequent passes

Gardening.
This reverts commit ca20aab384.
That commit causes generation of incorrect register names on
vm-noopt-simarm64-mac-be, and it seems to cause a disk full
error later on (making the bot purple).

Emit CFI information to teach gdb how to unwind Dart frames. Fixes unwinding for Mac x64 and Linux x64/ARM/ARM64. Unwinding already worked for iOS ARM64. Fixes unwinding on Android 6+ ARM.
Emit DWARF information about function inlining and line number mappings. Works with gdb, addr2line and llvm-symbolizer.
With --dwarf-stack-traces, also remove CodeSourceMaps from snapshots and change stack traces to a non-compliant form resembling Android's debuggerd output, which can be passed to ndk-stack.

Move optimizations for precompilation into separate file.
Remove precompilation-specific code from flow_graph_optimizer.cc.
Add precompilation-flags: They are const in the precompiled runtime. Started moving flags to use the new flag-definition macros.
Add libdart_lib_precompiled target.
Define PRECOMPILED_RUNTIME_MACRO in more places (dart_precompiled_runtime)

Remove -fdata-section again from the Linux build configuration: It prevented
some optimizations in gcc and clang - fewer things were recognized as constants.
Add const to pointers/arrays in some places to help compilers with determining
what is a constant. A common pattern is strlen of a string literal const char*,
or an array of function pointers.
Tested with gcc 4.8.4 / clang 3.4 and improves code qualtiy + reduces binary size.

In a next step, the i/o will be moved to the service isolate so that not all isolates have to import dart:io.
Fallout from this change:
1) Loading has become a tad slower. Will have to investigate why.
2) Errors that happen during loading (file not found, compilation error in an imported library) are no longer reported at the offending import clause. This can be fixed later if necessary by passing the import clause source location to the library tag handler.

The purpose of this change is twofold:
1. Source in the bin directory can now use the same assertions as
source in the vm directory. The ASSERT macro used by the code
in runtime/bin was just defined to use assert from the standard
C library.
2. Moving other implementation parts from runtime/vm to
runtime/platform (e.g. classes Monitor and Mutex) for sharing
between runtime/bin and runtime/vm will be easier as these
implementations rely on these assertion macros.
Created two gypi files for the platform directory. One for the
headers and one for the source. The source one is only included
when building the VM library and will be present in libdart.a
when the dart executable is linked.
All the code for asserts is still in the dart namespace.
Also re-arranged the order of includes to be alphabetically in
the files touched.
