cb27d09534 Fix bugs introduced by r4475: 
- RelinkPageListInChunkOrder might relink unused pages into the middle of a sequence of used pages. Filler objects should be placed at the beginning of such unused pages otherwise generic iterators (e.g. HeapObjectIterator) would not handle them correctly. 
- ObjectAreaEnd() should not be used as an allocation limit for pages from FixedSpace. Pages in such spaces do not use top page_extra_ bytes of object area.

968a524432 Add inlining of property load on ARM 
Generate inlined named property load for in-object properties. This uses the same mechanism as on the Intel platforms with the map check and load instruction of the inlined code being	patched by the inline cache code. The map check is patched through the normal constant pool patching and the load instruction is patched in place.

b8ba4deacc Reapply: Inline fast cases in string keyed load IC. 
(Fixed handling of out-of-bounds keys.)

String keyed load used to call STRING_CHAR_AT builtin that performs
two steps (get a char code, construct a one-char string from the
code), both of which have fast cases implemented as inline runtime
functions. In this chage most of the code from these functions is
extracted to a set of common generator functions in StringStubBase and
the fast cases are grouped together in the IC code.

61085478c6 Report approximated duration in milliseconds for profile nodes. 
The simple formula "ms = ticks * sampler_interval" doesn't work,
because e.g. on Linux, the actual sampling rate can be 5 times
lower than the one set up in the code. To calculate actual sampling
rate, current time is periodically queried and processed along with
actual sampling ticks count.

afc15bb48f Reapply load ICs for nonexistent properties. 
We need to be careful to check global property cells for the property
encountered during lookup.  Therefore, the ICs have to be specific to
the name of the property if global objects are involved.  In
principle, this means that we could get a large number of monomorphic
ICs for the same map if there is a global object in the prototype
chain.  However, since this is only done for normal load ICs and not
for keyed load ICs I do not expect this to be a problem.  I will
experiment with it once this goes in.

This is to make possible enabling usage of the new profiling subsystem
in Chromium without much hassle. The idea is pretty simple: unless the
new profiling API is used, all works as usual, as soon as Chromium
starts to use the new API, it will work too.

4f5ff869d3 C++ profiles processor: align browser mode with the old implementation, sample VM state. 
In browser (DevTools) mode, only non-native JS code and callbacks are reported.
Also, added "(garbage collector)" entry which accumulates samples count in GC state.
Trying to display "(compiler)" and "(external)" only brings confusion,
because it ends up in displaying scripts code under "(compiler)" node, and DOM
event handlers under "(external)" node, which looks weird.

9e76d99fb9 Percise rounding parsing octal and hexadecimal strings. 
Rounding happens when the number exceeds 53 bits of floating point mantissa. Current implemetation ignores digits after some limits. 0x1000000000000081 was rounded to 0x1000000000000100 while 0x100000000000008000001 was rounded to 0x100000000000000000000.
