7015fd2053 Make context register implicit for CallInterfaceDescriptors 
Up until now the context register was listed explicitly in each stub's
CallInterfaceDescriptor. This was problematic, because it was listed
first in the list of register parameters--which is fine for Crankshaft,
which is more or less built to handle the context as the first
parameter-- but not ideal for TurboFan, which adds the context at
the end of all function parameters. Now the context register is no
longer in the register list and can be handled appropriately by both
compilers. Specifically, this allows the FunctionType specified for
each CallInterfaceDescriptor to exactly match the parameter register
list.

dd85444951 [strong] Refactor ObjectStrength into a replacement for strong boolean args 
Boolean "is_strong" parameters have begun to proliferate across areas where
strong mode semantics are different. This CL repurposes the existing
ObjectStrength enum as a replacement for them.

3bce9c3afb New hydrogen instruction to reduce cost of growing an array on keyed stores. 
HMaybeGrowElements moves the situation where you actually have to grow
into deferred code. This means crankshaft doesn't have to spill registers
just to make the bounds comparison to see if it'll need to grow or not.

It makes the growing case a bit more expensive, but reduces the cost of
the general case.

97bee8e964 [strong] Fix inlining issue 
The Hydrogen representation for binops was never changed to care about the
language mode. We thought this was ok, but it turns out we need to keep track
of it to make sure inlining doesn't mess with the "strongness" of binops.

Also added more rigorous inlining testing.

c7851da4ae Introduce LanguageMode, drop StrictMode. 
This enables adding more language modes in the future.

For maximum flexibility, LanguageMode is a bitmask, so we're not restricted to
use a sequence of language modes which are progressively stricter, but we can
express the language mode as combination of features.

For now, LanguageMode can only be "sloppy" or "strict", and there are
STATIC_ASSERTS in places which need to change when more modes are added.

LanguageMode is a bit like the old LanguageMode when "extended" mode was still
around (see https://codereview.chromium.org/8417035 and
https://codereview.chromium.org/181543002 ) except that it's transmitted through
all the layers (there's no StrictModeFlag).

71bb00e261 Consistently use only one of virtual/OVERRIDE/FINAL. 
FINAL implies OVERRIDE, which in turn implies virtual, so there's no need to use
more than one of these. The Google C++ style guide even requires this, see
http://google-styleguide.googlecode.com/svn/trunk/cppguide.html#Inheritance.

While we're here, port r24662 to x87.

The net result is that v8 compiles again with a current clang.

b09989ec58 Refactor transitioning stores. 
There's actually no need to have the transition as part of the HStoreNamedField instruction. In fact, it is cleaner and faster to generate a separate HStoreNamedField for the transition map. This will also help to eliminate map stores with store elimination, as well as reduce register pressure for transitioning stores on ia32.

785bdf7c1e Don't add code dependencies eagerly for HCheckMaps. 
Instead of adding code dependencies on stable during
graph creation, we now add them during code generation
for those HCheckMaps that survived dead code elimination.

50d8259fea Fix crash in debug builds introduced with r21110. 
Basically we should not check for map deprecation during
code selection, because that may run on the concurrent
compiler thread. So the fix is to move this logic to the
code generation phase instead, which is always run on the
main thread.
