a691c693fb Fix lazy parsing heuristics to respect outer scope. 
This makes sure that a function literal is only parsed lazily when the
outer scope actually allows lazy compilation. Otherwise compilation will
crash due to a missing function body.

68c944c265 In-place shrinking of descriptor arrays with non-live transitions. 
Instead of overwriting non-live transitions with NULL_DESCRIPTORs, we remove them from the array by compacting the array (shifting live values to the left) and in-place trimming the array. If the final descriptor array contains no live values (only contained transitions which are now all cleared), we move bit_field3 back from the descriptor array to the map. The descriptor array itself will be collected in the next GC.

  and NotFound() also resets the type to NONEXISTENT.

e4f4aad2d1 x86/x64 port of Math.floor(x/y) to use integer division for specific divisor. 
Only handles when x is int32 and y is int32 constant.

BUG=v8:2038

Currently implemented by imul (not fpmul).
x86 and x64 algorithm differs a bit.
x86 implementation is kind of cumbersome, but I couldn't think of better ways.
