Revert "PR22877: When constructing an array via a constructor with a default argument...

Revert "clang/test/CodeGenCXX/array-default-argument.cpp: Satisfy targets that have x86_thiscallcc."

This reverts commit r302750 and its fixup r302757 because the test is
still breaking on some of the ARM bots.

array-default-argument.cpp:20:12: error: expected string not found in input
 // CHECK: {{call|invoke}}[[THISCALL:( x86_thiscallcc)?]] void @_ZN1AC1Ev([[TEMPORARY:.*]])
