e91b96922e [Compiler] Move construction of CompilationInfo into GenerateUnoptimizedCode
Moves the construction of CompilationInfo for unoptimized code into
GenerateUnoptimizedCode in preparation for making it owned by the
unoptimized compilation jobs (to be done in a followup CL).

This CL also adds a new constructor for creation of unoptimized
CompilationInfos with fields correctly initialized and updates the existing
constructor to he exclusively for optimized compilation. Finally, also moves
the call to RecordFunctionCompilation with LAZY_COMPILE_TAG recording into
FinalizeUnoptimizedCompilationJob where it is called for other unoptimized
compiles.

cd9e86a59e [inspector] move breakpoint management to native
My goal was to move breakpoint API to native with minimal changes around, so on inspector side we use v8::debug::BreakpointId instead of String16, on v8::internal::Debug we use i::BreakPoint object instead of break point object created inside of debug.js.

There are a lot of opportunities how we can improve breakpoints (at least we can avoid some of linear lookups to speedup implementation) but I think that as first step we need to remove mirrors/debug.js APIs.

Drive by: debugger-script.js and usage of debugger context in inspector code base.

and add builtin support for them.

Also adds TailCallRuntimeN operator to code-assembler which enables tail calling

1fc93f2e2d [Compiler] Enable use of seperate zones for parsing and compiling.
In order to allow parallel compilation of eager inner functions, we need to
seperate the zone used for parsing (which will be shared between all the
parallel compile jobs) and the zone used for compilation. This CL changes
CompilationInfo to require a zone (which can be different from the zone in
ParseInfo). We then seal the ParseInfo zone after parsing and analysis is done
to prevent any further allocation in that zone, so that it can be shared
(read-only) with the parallel compile jobs.

839b06b64f [Parse] ParseInfo owns the parsing Zone.
Moves ownership of the parsing Zone to ParseInfo with a shared_ptr. This is
in preperation for enabling background compilation jobs for inner functions
share the AST in the outer-function's parse zone memory (read-only), with the
and zone being released when all compilation jobs have completed.

This removes the {ParseInfo} constructor consuming a closure, replacing

ed18aa65ea Remove support for legacy const, part 1
Now that ES2015 const has shipped, in Chrome 49, legacy const declarations
are no more. This lets us remove a bunch of code from many parts of the
codebase.

In this patch, I remove parser support for generating legacy const variables
from const declarations. This also removes the special "illegal declaration"
bit from Scope, which has ripples into all compiler backends.

Also gone are any tests which relied on legacy const declarations.

Note that we do still generate a Variable in mode CONST_LEGACY in one case:
function name bindings in sloppy mode. The likely fix there is to add a new
Variable::Kind for this case and handle it appropriately for stores in each
backend, but I leave that for a later patch to make this one completely
subtractive.

Reason for revert:
It is not a good idea to call CallICStub from the builtin. It might be sensitive to the frame structure. Constructing a internal frame might cause problems. It is much better to inline the code  related to the type feedback vector into the builtin.
