Fixing a build breakage caused from a change in LLVM rL281019

[dvlahovski]

Summary

LLVM guys did some clean-up of the Attribute getters/setters
and because of that the build was failing.

lldb/trunk/source/Plugins/LanguageRuntime/RenderScript/RenderScriptRuntime/RenderScriptx86ABIFixups.cpp

for (auto call_inst : rs_callsites) {
     // get the function attributes
     llvm::AttributeSet call_attribs = call_inst->getAttributes();
 
     // iterate over the argument attributes
     for (size_t i = 1; i <= call_attribs.getNumSlots(); ++i) {
       // if this argument is passed by val
       if (call_attribs.hasAttribute(i, llvm::Attribute::ByVal)) {
         // strip away the byval attribute
-        call_inst->removeAttribute(
-            i,
-            llvm::Attribute::get(module.getContext(), llvm::Attribute::ByVal));
+        call_inst->removeAttribute(i, llvm::Attribute::ByVal);
         changed = true;
       }
     }
   }
 
   llvm::AttributeSet attr_byval =
       llvm::AttributeSet::get(module.getContext(), 1u, llvm::Attribute::ByVal);
