regis@google.com 3c063c8d4f Eliminate type checks that can successfully be performed at compile time.

asiva@google.com e360e4d1c9 Second set of changes for implementation of stack map support. 
- Added functionality to be able to build stack maps in the compiler and register them into the Code object during Code finalization.
- Merged code_generator_ia32_test.cc and code_generator_x64_test.cc into code_generator_test.cc as the two files were identical.

srdjan@google.com e2ab4d25fd Added stack overflow checks at backward branches in order to allow interrupting endless loops. Better code will detect if the loop calready contains calls and therefore can omit the extra check (in next compiler).

kmillikin@google.com 888a35df7f Add a stubbed-out implementation of FlowGraphCompiler for ia32 and arm. 
It bails out if FlowGraphCompiler::CompileGraph is called, all other public
API functions are UNIMPLEMENTED.

hausner@google.com 6d9abc5e3b StepOver, StepInto, StepOut 
Implement single stepping in the debugger.
- Add PC descriptors for function return
- functions to set temporary breakpoints on all
  locations in a function.
- patching/restoring of function return code pattern
- determine call target of instance calls

kmillikin@google.com 862dc2f03c Add enough compiler support to compile empty functions on x64. 
Implement a simple compilation visitor for the intermediate language.  Copy
code from the x64 code generator to support compilation of functions with no
arguments, no locals, and that return a literal.

Compiled code is not used, but it can be disassembled and visually checked
against the code from the old code generator.

srdjan@google.com a343a49338 Do not count invocations but usage of a function, i.e., increment a function's counter at IC calls and at return operations in unoptimized code. (TODO: increment count at static calls as well). There is no checking at method entry any more. The function counter reporting is not measuring the invocation count but much more how much time we spend in a method. Removed counter at backward branches. 
Renamed flags to:
--optimization_counter_threshold (default 2000)
--report_usage_count

hausner@google.com 4d3a5f658a Add PC descriptor for ret instruction 
Adding a new kind of PcDescriptor to mark the location of
function returns in generated code. This will be needed to
put a single-step breakpoint just before the function return.

Also adding a NOP instruction after the ret, so that the
function return code pattern adds up to 5 bytes, which is needed
to patch in a breakpoint call.

hausner@google.com 503e2219b8 First part of inspecting local variables 
This change introduces variable descriptors that describe the name, stack slot index, and source code stretch in which a variable is valid.

Activation frames in the stack trace now can enumerate the variables that are active in that frame.

Next step: fetch the value of variables from the stack.
