These are then restored upon `ContinuePendingUnwind`.
This stops us from forgetting where we needed to jump when we do extra
try-catches in finally blocks.

This is currently only used in the bytecode dump to annotate to where
unwinds lead per block, but will be hooked up to the virtual machine in
the next commit.
Now, the 'object-position' property gets properly parsed and is
provided to the rest of the ecosystem.
In the parser we use the same parsing as for the background-position,
which is not entirely correct but almost a <position>.
This patch adds the 'object-position' CSS property description to the
json for code generation.
Also the 'position' enum is added. The values of this enum are the
valid inputs to the object-position property from CSS Values-4.
The postitioning enum values are used by the position CSS property.
Unfortunately, the prior naming clashes with the CSS Values-4 type
named position, which will be implemented in a later commit.
Because slugify function accepts AK::String, which can hold unicode
code_points as well, heading text is normalised to ensure with NFD
form to ensure same binary respresentation of a particular string.
XZ writes filters in the order that they are used during compression, so
we need to process them in the reverse order while decompression.
This wasn't noticed earlier because we only supported the LZMA2 filter.
This makes the code a bit more readable and in conjunction with the
ModRM helper should prevent some operand ordering bugs.
This also includes one incidental bugfix:
`sign_extend_32_to_64_bits`, was not setting the `REX.R` bit when
appropriate,
And one size obvious optimization:
We may now elide the REX prefix on `xor eax, eax` as storing to a 32 bit
register clears the upper 32 bit of said register, which is wanted here.
This also widens the argument coverage of some helpers, to allow
memory offsets, this also consolidates the displacement size choosing.
This also stops us from some out argument ordering bugs, as we now just
need to look up the correct calling convention and call the correct
function.
