[gn build] Add build files for Target/X86/... and for tools/llc
The tablegen setup for Target/X86 is a bit different from the CMake build: In the CMake build, Target/X86/CMakeLists.txt has a single tablegen target that does everything. But some of the generated files are only used privately by a subproject, so in the GN build some of the tablegen invocations are smaller-scoped, mostly for build cleanliness. (It helps also a tiny bit with build parallelism since now e.g. the cpp files in MCTargetDesc can build after just 3 .inc files are generated instead of being blocked on all 13. But it's not a big win, since things depending on Target still need to wait for all 11, even though all .inc file use is internal to lib/Target.) Also add a build file for llc, since now all its dependencies have build files. Differential Revision: https://reviews.llvm.org/D55524 llvm-svn: 348903

# This build file has two parts:
4+
# 1. The actual //llvm/lib/Target build target, which is just a static
5+
# library containing the cpp files in this directory. It contains general
6+
# shared target code.
7+
# 2. Forwarding targets that forward to the concrete targets (X86, ARM, ...).
8+
# These are defined in subdirectories, and the forwarding names match
9+
# the names of the forwarding targets in CMake. They all (indirectly,
10+
# through CodeGen) depend on the //llvm/lib/Target build target.
11+
# (See also `gn help labels`).
12+
# The dependency chain is:
13+
# //llvm/lib/Target:TargetsToBuild (a target in this file) ->
14+
# /llvm/lib/Target/(X86|ARM|...) (in the subdirectories) ->
15+
# //llvm/lib/CodeGen ->
16+
# //llvm/lib/Target (a target in this file again)
17+
# Note that while this file appears twice in that stack, it's with different
18+
# targets in this file, so there's no cyclic dependency.
