Replace with `CFLAGS_EXTRAS+=-std=c++2a`

This comment looks misplaced.
================
Comment at: lldb/packages/Python/lldbsuite/test/lang/cpp/char8_t/main.cpp:1-7
+#include <cstring>
+
+int main (int argc, char const *argv[])
+{
+ char8_t c8 = u8'\0';
+ return 0; // Set break point at this line.
+}
----------------
It doesn't look like you actually need a running process for this at all. I think you could just make `c8` a global variable and inspect it from the executable image directly (`target variable c8`).

Comment at: lldb/source/Plugins/Language/CPlusPlus/CPlusPlusLanguage.cpp:857-862
+ cpp_category_sp, lldb_private::formatters::Char8StringSummaryProvider,
+ "char8_t * summary provider", ConstString("char8_t *"), string_flags);
+ AddCXXSummary(cpp_category_sp,
+ lldb_private::formatters::Char8StringSummaryProvider,
+ "char8_t [] summary provider",
+ ConstString("char8_t \\[[0-9]+\\]"), string_array_flags, true);
----------------
It looks like you're also adding formatters for `char8_t *` and `char8_t[N]`. I guess those should be tested too...
