ae65e281f3 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

a2dec6ab6b Fix layering by moving X86DisassemblerDecoderCommon to Support
This is used from llvm tblgen and the X86Disassembler - the only common
library (apart from TableGen, which probably doesn't make sense to have
as a dependency from a release tool (rather than a use-while-building-llvm
tool) of LLVM)

304b9bd5e0 Revert r234389. It really was needed but really should have been cstring instead of string.h

da144ed5a2 Canonicalize header guards into a common format.
Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Changes made by clang-tidy with minor tweaks.

bb9ac8f48d Don't provide two different definitions of ModRMDecision, OpcodeDecision, and ContextDecision in different source files (depending on #define magic).

b3f7e28cb6 Remove modifierType/Base from X86 disassembler tables as they are no longer used. Removes ~11.5K from static tables.

3e8b3f66be Sort the #include lines for utils/...
I've tried to find main moudle headers where possible, but the TableGen
stuff may warrant someone else looking at it.

3f200a7638 Add more indirection to the disassembler tables to reduce amount of space used to store the operand types and encodings. Store only the unique combinations in a separate table and store indices in the instruction table. Saves about 32K of static data.

18fa59f381 Table-driven disassembler for the X86 architecture (16-, 32-, and 64-bit
incarnations), integrated into the MC framework.  

The disassembler is table-driven, using a custom TableGen backend to 
generate hierarchical tables optimized for fast decode.  The disassembler 
consumes MemoryObjects and produces arrays of MCInsts, adhering to the 
abstract base class MCDisassembler (llvm/MC/MCDisassembler.h).

The disassembler is documented in detail in

- lib/Target/X86/Disassembler/X86Disassembler.cpp (disassembler runtime)
- utils/TableGen/DisassemblerEmitter.cpp (table emitter)

You can test the disassembler by running llvm-mc -disassemble for i386
or x86_64 targets.  Please let me know if you encounter any problems
with it.
