a71b7b0911 Fix a typo noticed by Peter Collingbourne. No one depends on this
working today, but it shouldn't corrupt state for some poor soul to
debug later.

1bfc9f8ff2 The TableGen parts of the CMake build are seriously broken. This fixes
one aspect of them by having them use the (annoying, if not broken)
proper library dependency model for adding the LLVMTableGen library as
a dependency. This could manifest as a link order issue in the presence
of separate LLVM / Clang source builds with CMake and a linker that
really cares about such things.

Also, add the Support dependency to llvm-tblgen itself so that it
doesn't rely on TableGen's transitive Support dependency. A parallel
change for clang-tblgen will be forthcoming.

b35552d440 Clean up a pile of hacks in our CMake build relating to TableGen.
The first problem to fix is to stop creating synthetic *Table_gen
targets next to all of the LLVM libraries. These had no real effect as
CMake specifies that add_custom_command(OUTPUT ...) directives (what the
'tablegen(...)' stuff expands to) are implicitly added as dependencies
to all the rules in that CMakeLists.txt.

These synthetic rules started to cause problems as we started more and
more heavily using tablegen files from *subdirectories* of the one where
they were generated. Within those directories, the set of tablegen
outputs was still available and so these synthetic rules added them as
dependencies of those subdirectories. However, they were no longer
properly associated with the custom command to generate them. Most of
the time this "just worked" because something would get to the parent
directory first, and run tablegen there. Once run, the files existed and
the build proceeded happily. However, as more and more subdirectories
have started using this, the probability of this failing to happen has
increased. Recently with the MC refactorings, it became quite common for
me when touching a large enough number of targets.

To add insult to injury, several of the backends *tried* to fix this by
adding explicit dependencies back to the parent directory's tablegen
rules, but those dependencies didn't work as expected -- they weren't
forming a linear chain, they were adding another thread in the race.

This patch removes these synthetic rules completely, and adds a much
simpler function to declare explicitly that a collection of tablegen'ed
files are referenced by other libraries. From that, we can add explicit
dependencies from the smaller libraries (such as every architectures
Desc library) on this and correctly form a linear sequence. All of the
backends are updated to use it, sometimes replacing the existing attempt
at adding a dependency, sometimes adding a previously missing dependency
edge.

Please let me know if this causes any problems, but it fixes a rather
persistent and problematic source of build flakiness on our end.

d538e24922 Changes for building Clang and others using LLVM as an external
library.

Installs tblgen (required by Clang).

Translates handling of user settings and platform-dependant options to
its own file, where it can included by another project.

Installs the .cmake files required by projects like Clang.

5b30f0a7eb TableGen.cmake: sometimes the .td file is not in the current directory
(clang/include/clang/Basic/StmtNodes.td, for instance, is tablegenned
from clang/include/clang/AST/CMakeLists.txt) so it is not contained on
the list of all .td files on the current source directory which is
used as the DEPENDS of the custom command. We must add the .td file to
the DEPENDS list of the custom command. Otherwise some .inc files are
not regenerated when the corresponding .td file changes.
