ebb44f0d30 Expose gc(true) to JavaScript, which triggers a scavenger GC. 
With the --expose_gc option, gc() is exposed to JavaScript. Currently gc() triggers a full GC.

To enable JavaScript to test the behavior of a scavenger GC, this patch exposes gc(true). If the first argument is true, gc(...) triggers a scavenger GC. Otherwise, gc(...) triggers a full GC.

BUG=
Test=Manually confirmed that gc() and gc(false) trigger a full GC and that gc(true) triggers a scavenger GC.

37759f4d64 Implement committed physical memory stats for Linux. 
The patch introduces CommittedPhysicalMemory function to
the Heap class that reports committed *physical* memory acquired
for the heap from the OS.
It is important because some OSes may defer actual committment on e.g.
first access to the region.
So reporting just plain committed size led to various weird artifacts
like showing V8 allocated memory higher than the whole process
private size.

d247c5e6c7 Change constant pool marker to be the unconditional, permanently undefined instruction. 
The previously-used instruction isn't guaranteed to always be undefined,
and the encoding used was conditional (failing the condition on an
undefined instruction is itself undefined and not guaranteed to
fault!). I would have like to use a more clever encoding (see bug 2963),
but we need the extra bits to encode the size of the constant pool.

063609280e Add a faster API for creating v8::Integer objects 
In WebKit, we have a small integer cache because calling v8::Integer::New is
slow. This patch adds a faster API for creating integers that requires the
caller to supply the v8::Isolate, saving us the work of looking up the isolate
in thread-local storage.
