[vectorIntrinsics+mask] RFR: 8272479: Fix a regression of rearrange intrinsic after JDK-8272479

[Jie Fu]

Hi all, 

After JDK-8272479, the following crash was observed on x86 with `-ea -esa -Xcomp -XX:CompileThreshold=100`


test Double256VectorTests.RearrangeDouble256VectorTests(double[-i * 5], shuffle[random]): success
test Double256VectorTests.RearrangeDouble256VectorTests(double[i * 5], shuffle[random]): success
test Double256VectorTests.RearrangeDouble256VectorTests(double[i + 1], shuffle[random]): success
test Double256VectorTests.RearrangeDouble256VectorTests(double[cornerCaseValue(i)], shuffle[random]): success
o114  ReplicateD  === _ o73  [[o340 ]]  #vectory[4]:{double}

--N: o114  ReplicateD  === _ o73  [[o340 ]]  #vectory[4]:{double}

   --N: o73  ConI  === o0  [[o166 o173 o114 ]]  #int:0
   IMMI  10  IMMI

   IMMI8  5  IMMI8

   RBX_REGI  50  loadConI0
   RCX_REGI  50  loadConI0

   RDI_REGI  50  loadConI0
   NO_RAX_RDX_REGI  50  loadConI0

This is because the type of broadcasted ZERO is incorrect.

Other affected tests include

jdk/incubator/vector/DoubleMaxVectorTests.java
jdk/incubator/vector/Float128VectorTests.java
jdk/incubator/vector/Float256VectorTests.java
jdk/incubator/vector/FloatMaxVectorTests.java
jdk/incubator/vector/Long256VectorTests.java
jdk/incubator/vector/LongMaxVectorTests.java


Let's fix it.

Thanks.
Best regards,
Jie
