  Changed paths:
    M clang-tools-extra/clangd/unittests/ModulesTests.cpp
    M clang/lib/Lex/Lexer.cpp
    M clang/unittests/Lex/CMakeLists.txt
    M clang/unittests/Lex/LexerTest.cpp

  Log Message:
  [Lex] Preambles should contain the global module fragment.

For applications like clangd, the preamble remains an important optimization
when editing a module definition. The global module fragment is a good fit for
it as it by definition contains only preprocessor directives.
Before this patch, we would terminate the preamble immediately at the "module"
