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.

This makes sure that we only record relocation slots for code target
patches that happen in marked objects. Unmarked ones might be visited
again, whereas marked ones are alive and will not be visited again.

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.
