Martin Storsjö 7b416c5e36 [llvm-readobj] [ARMWinEH] Print ARM64 packed unwind info
In addition to printing the individual fields, synthesize and
print the corresponding prolog for the unwind info (in reverse
order, to match how it's printed for non-packed unwind info).

Martin Storsjö f5e2ea9a43 [AArch64] Add asm directives for the remaining SEH unwind codes
Add support in llvm-readobj for displaying them and support in the
asm parsser, AArch64TargetStreamer and MCWin64EH for emitting them.

The directives for the remaining basic opcodes have names that
match the opcode in the documentation.

The directives for custom stack cases, that are named
MSFT_OP_TRAP_FRAME, MSFT_OP_MACHINE_FRAME, MSFT_OP_CONTEXT
and MSFT_OP_CLEAR_UNWOUND_TO_CALL, are given matching assembler
directive names that fit into the rest of the opcode naming;
.seh_trap_frame, .seh_context, .seh_clear_unwound_to_call

The opcode MSFT_OP_MACHINE_FRAME is mapped to the existing
opecode enum UOP_PushMachFrame that is used on x86_64, and also
uses the corresponding existing x86_64 directive name
.seh_pushframe.

Fangrui Song 8be28cdc52 [Object] Change getSectionName() to return Expected<StringRef>
Summary:
It currently receives an output parameter and returns
std::error_code. Expected<StringRef> fits for this purpose perfectly.

Chandler Carruth 2946cd7010 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.

Zachary Turner 88bb163f81 Move llvm-readobj/StreamWriter to Support.
We wish to re-use this from llvm-pdbdump, and it provides a nice
way to print structured data in scoped format that could prove
useful for many other dumping tools as well.  Moving to support
and changing name to ScopedPrinter to better reflect its purpose.

Rui Ueyama 062c406a85 Support: Delete {aligned_,}{u,}{little,big}8_t
The byte has no endianness, so these types don't make sense.
uint8_t should be used instead.

Benjamin Kramer a7c40ef022 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.

Rafael Espindola 3acea39853 Don't use 'using std::error_code' in include/llvm.
This should make sure that most new uses use the std prefix.

Case insensitive case preserving file systems are not a good choice for
development.

Saleem Abdulrasool e6971cab30 tools: initial implementation of WoA EH decoding
Add support to llvm-readobj to decode Windows ARM Exception Handling data.  This
uses the previously added datastructures to decode the information into a format
that can be used by tests.  This is a necessary step to add support for emitting
Windows on ARM exception handling information.

A fair amount of formatting inspiration is drawn from the Win64 EH printer as
well as the ARM EHABI printer.  This allows for a reasonably thorough look into
the encoded data.
