[debuginfo] Include dwo_name in the split unit to improve dwp diagnostics
When multiple DWP files are merged together and duplicate DWO IDs are
found it's currently difficult to give an actionable error message - the
DW_AT_name of the CU could be provided, but might be identical (if the
same source file is built into two different configurations), which
doesn't help the user identify the problem.
When no intermediate DWP files are generated, the path to the two DWO
files could be provided - but is lost once the DWOs are merged into a
DWP.
So, include the name of the DWO (dwo_name) in the split file so that
collissions involving a source CU from a DWP can be better diagnosed.

[LAA] Support memchecks involving loop-invariant addresses
We used to only allow SCEVAddRecExpr for pointer expressions in order to
be able to compute the bounds. However this is also trivially possible
for loop-invariant addresses (scUnknown) since then the bounds are the
address itself.
Interestingly, we used allow this for the special case when the
loop-invariant address happens to also be an SCEVAddRecExpr (in an outer
loop).
There are a couple more loops that are vectorized in SPEC after this.
My guess is that the main reason we don't see more because for example a
loop-invariant load is vectorized into a splat vector with several
vector-inserts. This is likely to make the vectorization unprofitable.
I.e. we don't notice that a later LICM will move all of this out of the
loop so the cost estimate should really be 0.

Avoid UB when creating empty atoms. NFC.
The stack-size.yaml test had an empty atom content array. This is
legal, but asking a BumpPtrAllocator for 0 sized data may not be
legal. Instead just avoid requesting any data when we can just return
an empty ArrayRef instead.

Avoid UB deref of nullptr to reference. NFC.
Its possible for file to have no entry atom which means that there
is no atom to check for being a thumb function. Instead just skip
the thumb check and set the entry address to 0, which matches the
current behaviour of getting a default initialised int from a map.

Use a memcpy to avoid unaligned store UB.

Use unaligned read to fix UB. NFC.
We were casting a potentially unaligned pointer to uint32_t and
dereferencing. As the pointer ultimately comes from the object file,
there's no way to guarantee alignment, so use the little32_t read instead.
Also, little32_t knows about endianness, so in theory this may have broken on
big endian machines.
