[test] %clang_cc1 -emit-llvm: remove redundant -S

Also replace aarch64-none-linux-gnu (none can indicate an OS as well) with aarch64

This addresses the issue found in:
https://lab.llvm.org/buildbot/#/builders/245/builds/7882

This time, the issue was that not every platform has the same alignment
values, so those were removed from the test case.

[C2x] Update 'nullptr' implementation based on CD comments

2023-05-03T18:50:15+00:00

We filed some CD ballot comments which WG14 considered during the
ballot comment resolution meetings in Jan and Feb 2023, and this
updates our implementation based on the decisions reached. Those
decisions were (paraphrased for brevity):

US 9-034 (REJECTED)
  allow (void *)nullptr to be a null pointer constant
US 10-035 (ACCEPTED)
  accept the following code, as in C++:
  void func(nullptr_t); func(0);
US 22-058 (REJECTED)
  accept the following code, as in C++:
  nullptr_t val; (void)(1 ? val : 0); (void)(1 ? nullptr : 0);
US 23-062 (REJECTED)
  reject the following code, as in C++:
  nullptr_t val; bool b1 = val; bool b2 = nullptr;
US 24-061 (ACCEPTED)
  accept the following code, as in C++:
  nullptr_t val; val = 0;
US 21-068 (ACCEPTED)
  accept the following code, as in C++:
  (nullptr_t)nullptr;
GB-071 (ACCEPTED)
  accept the following code, as in C++:
  nullptr_t val; (void)(val == nullptr);

This patch updates the implementation as appropriate, but is primarily
focused around US 10-035, US 24-061, and US 23-062 in terms of
functional changes.
