RFR 8211272: x86_32 build failures after JDK-8210764 (Update avx512 implementation)

[Aleksey Shipilev]

Bug:
  https://bugs.openjdk.java.net/browse/JDK-8211272

It is a trivial mistake: the braces got unbalanced when _LP64 is not defined, which is the case for
x86_32 build. I would not bother to run it through jdk-submit.

Fix:

diff -r eb3e72f181af src/hotspot/cpu/x86/c1_LIRAssembler_x86.cpp

             }
             assert(!tmp->is_valid(), "do not need temporary");
             __ andpd(dest->as_xmm_double_reg(),

Testing: x86_32 build, x86_64 build
