55e924c595 Fix CNLT regression. 
This happens when a map A with no descriptors in fast_holey_elements
mode first gets some properties, making it share descriptor arrays with
a map B to which it transitions. Then map A transitions elements kind to
dictionary_elements in map C. C stores the empty_descriptor_array in its
own transition array. When adding a property to C, C transitions to D
and shares the descriptors. If D dies, a CNLT clears the transition
array of C, making the descriptor array of A (and thus also of B) shine
through. If a property is now added to an object in state C, it'll inherit
all the properties of A (and B). If those properties had high field indices,
we do not have a large enough backing store for the single newly added
property, and we'll write out of bounds.

Although this doesn't hurt currently, it hurts any future compiler
pass relying on the invariant that no operand is NULL.

a92a9c8a2c MIPS: Changed "marked" nops to use sll(zero_reg, at, type). 
We use marking bits in nops (in the 'sa' field) for debug markers, and for some IC stuff. A normal NOP in mips is sll(zero_reg, zero_reg, 0), where the 0 is a 5 bit immediate field in 'sa'.

See enum NopMarkerTypes at around line 654 of assembler-mips.h

The problem is that these markers use encodings that are reserved for the 'ssnop' and 'ehb' instructions. These are instructions used for hazard barriers.

It does not break anything, but it will slow things down a little bit as some pipeline stages are cleared, etc.

This commit changes the "marked" NOPs to sll(zero_reg, at, type) instructions, which is also a NOP operation on MIPS.

974a2268bb Implement committed physical memory stats for Linux. 
The patch introduces CommittedPhysicalMemory function to the Heap class
that reports committed *physical* memory acquired from the OS.
It is important because some OSes may postpone actual commitment on e.g.
first access to the previously committed region.
So reporting just plain committed size led to various weird artifacts
like DevTools showing V8 allocated memory higher than the whole process
private size.

aba09dcf2e Allow partial scanning of large arrays in order to avoid 
mark stack overflow.  This is a reland of r12609 -
