74c730a08d [turbofan] Add mjsunit tests for try-catch-finally and OSR. 
This adds some basic tests of the interaction between try-catch and
try-finally statements and OSR in TurboFan. The try-osr test suite
follows the structure of try-deopt closely.

b715329a15 [turbofan] Split --turbo-exceptions into two flags. 
This allows try-catch and try-finally constructs to be separately
enabled and disabled. We plan to stage try-catch support soon.

that one side cannot be a String (or turn into a string via

Also remove bunch of useless DoNotCrash tests for the scheduler that are

abc35080b3 Add a MathFloor stub generated with TurboFan 
This stub will be used as the basis of a Math.floor-specific CallIC to
detect and track calls to floor that return -0.

Along the way:
- Create a TurboFanCodeStub super class from which the StringLength and
MathRound TF stubs derive.
- Fix the ugly hack that passes the first stub parameter as the "this"
pointer in the the TF-compiled JS function.
- Fix bugs in the ia32/x64 disassembler.

4d12e94801 Port CallSite methods to C++. 
The goal is to port all of error stack trace formatting to C++.
We will do this bottom up, by first porting helper functions.

Eventually, CallSite methods will only be used when a custom
error stack trace formatter is defined via Error.prepareStackTrace.

021f738127 Treat HArgumentsObject as a safe use during Uint32 analysis phase. 
Deoptimization infrastructure already handles it correctly.

This change fixes repetitive deoptimizations in the code like this:

    var u32 = new Uint32Array(1);
    u32[0] = -1;

    function tr(x) { return x|0; }
    function ld() { return tr(u32[0]); }

    while (true) ld();

Currently inlined tr will contain HArgumentsObject that is considered uint32-unsafe use and prevents u32[0] from becoming uint32 load - instead a speculative int32 load is generated which just deopts.

b7dc9c580a [turbofan] Remember types for deoptimization during simplified lowering. 
With this change, we remember the types of frame state inputs (in a new
operator, called TypedStateValues). Instead of inferring the value types
when building translations, we used the recorded types.

The original approach was not reliable because the passes after
simplified lowering can change node types, and this in turn confuses
the translation builder.

6f559b7ec3 [turbofan] Fix lazy deopt for JSToNumber conversions in binary operations. 
This slightly hacky change provides lazy deopt points for to-number conversions in binops: When we deopt from a to-number conversion, we create a frame state with the already-converted value(s) so that we do not repeat the side effect of the conversion.

d016387e81 [turbofan] Add test coverage for deopt within try-catch. 
This just contains test, no fixes. Note that some of the tests are
still disabled because they either fail or we don't want ClusterFuzz
to pick up the flag yet.

4c302ca290 Make it easier to test OSR with %OptimizeOsr() runtime call. 
This call triggers OSR for the current function. And also allows explicitly testing OSR on the top-level code.
