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.

srdjan@google.com 0912e4ded7 More code for ia32, more shared code. 
CreateArrayComp, EqualityCompareComp, StoreStaticField, LoadStaticField, StoreIndexedComp, StoreInstanceFieldComp, Throw, Rethrow, AssertBooleanComp.
Made more code shared, which has the disadvantage od splitting MakeLocationSummary from EmitNativeCode. Discuss.

vegorov@google.com 9125248ea2 In generated code for x64 don't load object's class directly from class_ field. 
Instead look it up in class table by class index taken from object's tags.
