Reviewers: danno,
Description:
Fix a register assignment bug in typed array stores without SSE3 available.
The old code used a separate HToInt32 instruction which had a wrong register
constraint for the input register which caused wrong result when the stored
value
is used after a typed array store. (UseRegister instead of UseTempRegister)
when
no
SSE3 is available.
This change fixes it by replacing HToInt32 with the corresponding HChange
instruction which has correct register contraints.
