f81d6fe75c Adjust a ValueObjectChild's offset when the child is a bitfield
If a bitfield doesn't fit into the child_byte_size'd window at
child_byte_offset, move the window forward until it fits.  The problem
here is that Value has no notion of bitfields and thus the Value's
DataExtractor is sized like the bitfields CompilerType; a sequence of
bitfields, however, can be larger than their underlying type.

This was not in the big-endian-derived DWARF 2 bitfield attributes
because their offsets were counted from the end of the window, so they
always fit.

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.

ae6ca2fc3f Allow IRInterpreter to deal with non-power-of-2 sized types to support some bitfield accesses.
Summary:
For some bitfield patterns (like the one added by this commit), Clang will
generate non-regular data types like i24 or i48. This patch follows a
pretty naive approach of just bumping the type size to the next power of 2.
DataExtractor know how to deal with weird sizes. The operations on Scalar
do not know how to deal with those types though, so we have to legalize the
size when creating a Scalar.

cae0855a62 DWARF layout for bitfields is wrong when the bit offset is negative.
Some older versions of clang emitted bit offsets that were negative and these bitfields would have their bitfield-ness stripped off and it would cause a clang assertion in clang assertions were enabled. I updated the bitfield C test to make sure we don't regress.

c432c8f856 Move lldb/test to lldb/packages/Python/lldbsuite/test.
This is the conclusion of an effort to get LLDB's Python code
structured into a bona-fide Python package.  This has a number
of benefits, but most notably the ability to more easily share
Python code between different but related pieces of LLDB's Python
infrastructure (for example, `scripts` can now share code with
`test`).
