If an address_space attribute is defined in a macro, print the macro instead
when diagnosing a warning or error for incompatible pointers with different
address_spaces.

We allow this for all attributes (not just address_space), and for multiple
attributes declared in the same macro.

Previously for the different purposes we need to get the active/common
parallel level and with full runtime we iterated over all the records to
calculate this level. Instead, we can used the warp-based parallel level
counters used in no-runtime mode.

r359717 added clang-check as a dep of check-clang unconditionally
because I had missed lit.local.cfg in test/Tooling.

Instead, only add clang-check to the tools if the analyzer is enabled,
since the build target only exists then, and since all tests using
clang-check are skipped when the analyzer is disabled.

The unwind tables (`.eh_frame`, `.arm.extab`) add a significant chunk of data to
the final binaries.  These should not be needed normally, particularly when
exceptions are disabled.  This enables shrinking `lldb-server` by ~18% (3 MiB)
when built with gold.

This patch inverses the values returned by `addName` and

This restructures the initialization path to move the ObjectContainer

Summary:
Fixes PR41677

Consider:
  template <typename LHS, typename RHS> constexpr bool is_same_v = false;
  template <typename T> constexpr bool is_same_v<T, T> = true;
  template constexpr bool is_same_v<int, int>;

Before this change, when emitting debug info for the
`is_same_v<int, int>` global variable, clang would crash because it
would try to use the template parameter list from the partial
specialization to give parameter names to template arguments. This
doesn't work in general, since a partial specialization can have fewer
arguments than the primary template. Therefore, always use the primary
template. Hypothetically we could try to use the parameter names from
the partial specialization when possible, but it's not clear this really
helps debugging in practice.

Two tests cannot share the same name, because they will generate an
identical trace file. When that happens, this can lead to a race
condition where dotest fails when trying to move both files into the
trace directory, because the file has already been moved. Additionally,
the trace will have been overwritten by the test that finishes last.

check the address space of the pointee type instead of the pointer
type to decide whether an address space cast is required.

Revert rL359778 : [clangd] Fix code completion of macros defined in the preamble region of the main file.

Summary:
This is a tricky case (we baked the assumption that symbols come from
the preamble xor mainfile pretty deeply) and the fix is a bit of a hack:
We look at the code to guess the macro names, and deserialize them from
the preamble "by hand".
