Fix the test zlib conditional to use LLVM_ENABLE_ZLIB value when
building stand-alone. The HAVE_LIBZ is not available when performing
a stand-alone build. Since the zlib support is a feature of
the underlying LLVM library, it exports the actual status as the final
value of LLVM_ENABLE_ZLIB in LLVMConfig.
While at it, canonicalize the boolean value into 0/1 and remove unused
CMake definitions (most likely copied from clang).

Use both LLD- and LLVM-specific binary&library directories when LLD is
being built stand-alone. This ensures that the freshly built tools and
libraries are found and used correctly.
Without this patch, the test suite uses LLVM_TOOLS_DIR and LLVM_LIBS_DIR
to locate lld, and set PATH and LD_LIBRARY_PATH. When doing
a stand-alone builds, these variables represent the installed LLVM.
As a result, tests either fail due to missing lld executables/libraries
or use an earlier installed LLD version rather than the one being built.
To solve this, an additional LLD_TOOLS_DIR and LLD_LIBS_DIR variables
are added that are populated using LLVM_*_OUTPUT_INTDIR. Those variables
are populated with directories used to output built executables
and libraries. In stand-alone builds, they represent the directories
used by LLD. In integrated builds, they have the same values as
LLVM_*_DIR and therefore using them does not harm.
The new variables are prepended to PATH and LD_LIBRARY_PATH to ensure
that freshly built binaries are preferred over potentially earlier
installed ones. Furthermore, the resulting PATH is used to locate tools
for substitutions since the search includes both tools built as part of
LLD and of LLVM.

At the moment almost every lit.site.cfg.in contains two lines comment:
## Autogenerated by LLVM/Clang configuration.
# Do not edit!
The patch adds variable LIT_SITE_CFG_IN_HEADER, that is replaced from
configure_lit_site_cfg with the note and some useful information.
