21da12a983 [Compiler] Remove CompileDebugCode and EnsureBytecode and replace with Compile
Removes the Compiler::CompileDebugCode and Compiler::EnsureBytecode functions
and replaces them with a Compiler::Compile(Handle<SharedFunctionInfo> shared)
function. The code in compiler.cc is refactored to use this function to compile
the SharedFunctionInfo when compiling a JSFunction.

Also does some other cleanup:
 - Removes CompileUnoptimizedFunction and inlines into new Compiler function
 - Moves code to create top level SharedFunctionInfo into CompilerTopLevel and
   out of FinalizeUnoptimizedCompile.

961a2c885d [fullcodegen] Remove ability to compile with Full-Codegen.
Removes the pathways to use Full-Codegen from compiler.cc. Also removes all
paths to optimize using AstGraphBuilder, which relies on Full-codegen.
Cleans up ast-numbering, runtime-profiler and some runtime functions to
remove now dead code.

This makes Full-codegen and AstGraphBuilder dead, but doesn't remove their
code yet, that will be done in a followup CL to keep things reviewable.

the call to RecordFunctionCompilation with LAZY_COMPILE_TAG recording into
FinalizeUnoptimizedCompilationJob where it is called for other unoptimized

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.

a72b2f88a8 [arm] Restrict grouping pushes before a TailCall to registers only
We optimize parallel moves performed before a TailCall by grouping adjacent
pushes. This way, we may use a single instruction to push multiple registers at
once. However, we also have support for pushing immediates and stack slots for
which the benefit is questionnable therefore this patch removes support for
them.

Concerning immediate pushes, it looks like a mistake since we do not have
support for this case in `AssembleMove` so this patch removes it. Furthermore,
if we add a test for this case, we see that a `push ip` instruction is
generated, effectively pushing whatever was in `ip` at the time instead of
pushing a constant.

Concerning stack slot pushes, we generate a more or less equivalent sequence of
instructions.

Finally, grouping floating point pushes is not used anywhere so this patch
removes support for this also.

c445e1e96b [Compiler] Remove EnsureBaseline.
We only optimize functions which are already compiled, so there is no need
to ensure baseline in pipeline.cc, and since ast-graph-builder doesn't
do inlining, there are no other uses.

05207b098a [Interpreter] Replace --ignition flag with a --stress-fullcodegen
Removes the --ignition flag which is now on by default. Adds a
--stress-fullcodegen flag which enables running all functions supported
by fullcodegen to be compiled by fullcodegen.

This will enable moving parser internalization later when we are not

cleared when the result is 32 bits. This change fixes the bug mentioned
below. Clearing the upper 32 bits is also done on x64.

4ea4e7294e [turbofan] Replace uninitialized JSCall nodes with SOFT deopt.
Uninitialized property accesses are replaced with SOFT deopts in
TurboFan, but uninitialized JSCall nodes are not, and instead they
just stick around and are also not being inlined because the heurstic
in TurboFan doesn't consider those candidates since their call frequency
is below the threshold. This unifies the behavior and also replaces
uninitialized calls with SOFT deopts, addressing some inconsistency in
optimization behavior as discovered by Brian White of Node for example

8d921ca7f3 [turbofan] Remove --turbo shorthand for --turbo-filter.
This removes the --turbo flag and solely relies on the filter pattern
provided via --turbo-filter when deciding whether to use TurboFan. Note
that disabling optimization wholesale can still be done with --no-opt,
which should be used in favor of --no-turbo everywhere.

Also note that this contains semantic changes to the TurboFan activation
criteria. We respect the filter pattern more stringently and no longer
activate TurboFan just because the source contains patterns forcing use
of Ignition via {AstNumberingVisitor::DisableFullCodegenAndCrankshaft}.

Reland d8bfdb7a99

Original commit message:
If alignment parameter is set, the memory returned by the
StackSlot operator will be aligned according to the parameter.

The implementation goes like this. If alignment parameter is set
we allocate a bit more memory than actually needed and so we
can move the beginning of the StackSlot in order to have it aligned.

3. Extend typed lowering of module loads and stores such that if
   the operand is a Module constant, we constant-fold the cell load.
   That is, a JSLoadModule with a Module HeapConstant input becomes
   a LoadField with a Cell HeapConstant input, and similarly for
