Florian Schneider d8677964a3 Move precompilation-related flags to flags list. 
They become compile-time constants in the precompiled runtime, and in product mode.

In precompiled product mode, the precompiled value has precedence.

The default value of print_stop_message was architecture specific.

Florian Schneider d76fe1eacd Clean up global variables related to precompilation. 
Replace always_optimize_ and allow_recompilation_ with
 FLAG_precompilation and !FLAG_precompilation.

They are equivalent and set only once according to the
--precompilation flag

Srdjan Mitrovic fe4a5d7672 This adds a mechanism to invalidate code that was generated in the background. The invalidation can happen if a relevant event was invoked between background compilation start and installation of code (e.g, field type invalidatet, subclasses added, deferred loading). 
We introduce 3 invalidation generation counters: CHA, field and library prefixes. If one of the counters was incremented during compilation, and is relevant for that compilation, the code installation is skipped since that code may have become invalid in the meantime.

Add BackgroundCompilationResult that remembers the 3 invalidation generations.

The generational counter can rollover, which is OK.

Florian Schneider bac82e2592 VM: New calling convention for generated code. 
Instead of calling code object directly, call indirectly and
pass the code object in a register. The object pool is then loaded from
the code object. This is another preparation step for making generated code
relocatable.

All non-ia32 platforms:
No entry patching.

ARM:
PC marker (now code object) moves to the same place as on x64 (below saved PP, above saved FP).
R9 is now used as PP, R10 as CODE_REG.
