b854e64f61 [X86Disassembler] Unify the EVEX and VEX code in emitContextTable. Merge the ATTR_VEXL/ATTR_EVEXL bits. NFCI
Merging the two bits shrinks the context table from 16384 bytes to 8192 bytes.

Remove the ATTRIBUTE_BITS macro and just create an enum directly. Then fix the ATTR_max define to be 8192 to reflect the table size so we stop hardcoding it separately.

d8490747ad [X86] Merge the different CMOV instructions for each condition code into single instructions that store the condition code as an immediate.
Summary:
Reorder the condition code enum to match their encodings. Move it to MC layer so it can be used by the scheduler models.

This avoids needing an isel pattern for each condition code. And it removes
translation switches for converting between CMOV instructions and condition
codes.

Now the printer, encoder and disassembler take care of converting the immediate.
We use InstAliases to handle the assembly matching. But we print using the
asm string in the instruction definition. The instruction itself is marked
IsCodeGenOnly=1 to hide it from the assembly parser.

This does complicate the scheduler models a little since we can't assign the
A and BE instructions to a separate class now.

I plan to make similar changes for SETcc and Jcc.

6b547686c5 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.

26b584c691 Remove \brief commands from doxygen comments.
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

cb6b3afcb2 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)
