This includes only the taken branch of conditional sections.
The API allows for producing a stream for a particular PP branch, which
will be used later for the secondary GLR parses of not-taken branches.

In files where different preprocessing paths are possible, our goal is to
choose a preprocessed token sequence which we can parse that pins down as much
of the grammatical structure as possible.
This forms the "primary parse", and the not-taken branches get parsed later,
and are constrained to be compatible with the primary parse.
Concretely:
int x =
#ifdef // TAKEN
2 + 2 + 2 // determined during primary parse to be an expression
#else
2 // constrained to be an expression during a secondary parse
#endif

This reverts commit 049f4e4eab.
The problem was a stray dependency in CLANG_TEST_DEPS which caused cmake
to fail if clang-pseudo wasn't built. This is now removed.
This should make clearer that:
- it's not part of clang proper
- there's no expectation to update it along with clang (beyond green tests)
- clang should not depend on it
This is intended to be expose a library, so unlike other tools has a split
between include/ and lib/.
The main renames are:
clang/lib/Tooling/Syntax/Pseudo/* => clang-tools-extra/pseudo/lib/*
clang/include/clang/Tooling/Syntax/Pseudo/* => clang-tools-extra/pseudo/include/clang-pseudo/*
clang/tools/clang/pseudo/* => clang-tools-extra/pseudo/tool/*
clang/test/Syntax/* => clang-tools-extra/pseudo/test/*
clang/unittests/Tooling/Syntax/Pseudo/* => clang-tools-extra/pseudo/unittests/*
#include "clang/Tooling/Syntax/Pseudo/*" => #include "clang-pseudo/*"
namespace clang::syntax::pseudo => namespace clang::pseudo
check-clang => check-clang-pseudo
clangToolingSyntaxPseudo => clangPseudo
The clang-pseudo and ClangPseudoTests binaries are not renamed.
