asiva@google.com eaebf15f43 Fix for issue 14790 - Crash when using dartium devtools 
The stack frame iteration during GC was missing one slot in stub frames that
did not save the pool pointer.

- This change makes all stub frames uniform, i.e they always save/restore the pool pointer. This ensures that we will traverse all slots on the stack.

- A new constant called kFirstObjectSlotFromFp has been added which is used as the slot to start stack traversal.

(The ARM and MIPs changes will be in a different CL)

zra@google.com df2054dae7 Sets a register aside on x64 for use as a pool-pointer. It is loaded and restored from the code object on Frame entry and exit. All LoadObject calls that can, and many calls and jumps through ExternalLabels now use the pool-pointer. The --compiler-stats flag when running dart2js indicates that code size is reduced ~13%, and more is probably possible.

fschneider@google.com cfab482b84 Follow-up fix to my change to IsPowerOfTwo: Alignment of one means no alignment, not zero. 
We assert that the alignment is a power of two. Therefore, platforms that do not need 
alignment should return alignment of one instead of zero.

fschneider@google.com 3cd9fa513f Fix bug in the x64 assembler's movw instruction. 
The order of prefixes was wrong.  The operand size prefix (0x66)
must occur before the REX prefix.  From the instruction set reference:

[...]the REX prefix byte must immediately precede the opcode byte or
the escape opcode byte (0FH). [...]

Also, make movw(reg, addr) unavailable, consistent with ia32.
