This patch fixes the errors https://lab.llvm.org/staging/#/builders/195/builds/4464 like

File "llvm-project/lldb/test/API/commands/expression/import-std-module/array/TestArrayFromStdModule.py", line 55, in test
    self.expect_expr("a.at(0)", result_type=value_type, result_value="3")
Hint: The expression tried to call a function that is not present in the target, perhaps because it was optimized out by the compiler.

Note adding the usage of a.at(0) to main.cpp did not help.
It is the alternative to #98701.

Note adding the usage of `a.at(0)` to main.cpp did not help.
It is the alternative to llvm#98701.

As mentioned in #98701 (comment), the test deliberately omits at from debug-info.
