6093d0dbf5 Inline NumberToString 
NumberToString in runtime JavaScript is inlined through a call to a stub. Currently the stub only checks the number string cache and only if the number is a smi. Code is shared with the inlining of number string cache lookup when adding a smi to a string.

dbe99e405a Introduce number type information in the virtual frame. 
Each frame element gets a new attribute with number type information. A frame element can be: 

- smi 
- heap number 
- number (i.e. either of the above) 
- or something else. 

The type information is propagated along with all virtual frame operations. 
Results popped from the frame carry the number information with them.

Two optimizations in the code generator make use of the new 
information: 
- GenericBinaryOpSyub omits map checks if input operands are numbers. 
- Boolean conversion for numbers: Emit inline code for converting a number (smi or heap number) to boolean. Do not emit call to ToBoolean stub in this case.

46020b3169 Probe the symbol table for two character strings in native code 
All two character string results from adding two strings and from sub string used to be handled in the runtime system as a lookup in the symbol table was done before allocating a new string. The native code for string add and sub string now probes the symbol cache for two character strings to avoid the runtime call. If the result string is not found in the symbol table within a fixed number of probes a new string is just allocated. Newly allocated two character strings are not added to the symbol table immediately.

4a2c81d3b0 Add last use data flow information to the fast code generator. 
This change add simple local live variable information to 
the fast code generator.  It supports only AST nodes that 
are accepted by the syntax checker.

Each variable use points to a variable definition structure
which contains the last use of the definition.

To determine whether a variable is live after a certain point
we can check whether its last use occurs later in the evaluation
order defined by the AST labeling number.

The new information is currently only printed out together with
the IR and not yet used for code generation.

638cb4f91d Always load the JavaScript builtins code entry from the JavaScript 
function instead of baking in the address of the first one that we see

This removes the need for fixups processing and makes the stubs safe
when there is no natives cache and therefore multiple versions of the
builtin functions.

30cf88af6b Restrict the syntax that we aggressively optimize. 
Do not use the speculative compiler for functions with other than one
statement in the body, and do not use it if subexpressions can have
side effects.  Bailing out to the beginning of the full code is not
sound if side effects have already occurred.

Add tests that would fail without the restrictions.

9b5c312bfc Initial implementation of fast path operation for bitwise OR. 
Support a binary operation (bitwise OR) so long as it's not nested in
the left subexpression.  This ensures that the expression stack never
has height greater than two and so can be kept fully in registers.

The bounded expression stack height and the absence of any side
effects on the fast path allows us to still bailout out to the very
beginning of the function if any of our fast-path checks fail.

503bbeb8c4 Change GenerateLoadStringLength to have two scratch registers on all platforms. This is needed so that the LoadIC can pass the receiver in a register, and not have it overwritten, and also simplifies the code.

df1df78c48 Changed fuzzer to randomly remove half of the arguments when running 
on functions that takes five or more arguments. Original version runs
for a long time when there is 5 arguments in a runtime function (45+
seconds). The fuzzer can be run with all arguments on all functions
regardless of the number of arguments by setting
RUN_WITH_ALL_ARGUMENT_ENTRIES to true in fuzz-natives.js

0d6b85b812 Added helper functions for fixed register allocation. 
Added helper functions to the fast code generator for temporary, ad hoc
fixed register allocation.  Also inlined some helper functions that had only
one call site to simplify the code generator API for now.
