[llvm-readobj/llvm-readelf] - Reimplement dumping of the SHT_GNU_verneed
This is similar to D70495, but for SHT_GNU_verneed section. It solves
the same problems: different implementations, lack of error reporting
and no test coverage.

[ExecutionEngine] Add a jitTargetAddressToFunction utility function.
jitTargetAddressToFunction takes a JITTargetAddress and returns a
pointer of the given function pointer type suitable for calling to
invoke the function at the target address.
jitTargetAddressToFunction currently behaves the same as
jitTargetAddressToPointer, but in the near future will be updated to
perform pointer signing on architectures that require it (e.g. arm64e).
For this reason it should always be preferred when generating callable
pointers for JIT'd functions.

[ORC] Add a runAsMain utility function to ExecutionUtils.
The runAsMain function takes a pointer to a function with a standard C
main signature, int(*)(int, char*[]), and invokes it using the given
arguments and program name. The arguments are copied into writable
temporary storage as required by the C and C++ specifications, so
runAsMain safe to use when calling main functions that modify their
arguments in-place.
This patch also uses the new runAsMain function to replace hand-rolled
versions in lli, llvm-jitlink, and the SpeculativeJIT example.

[llvm-readelf/llvm-readobj] - Check the version of SHT_GNU_verneed
section entries.
It is a follow-up for D70826 and it is similar to D70810.
SHT_GNU_verneed contains the following fields:
`vn_version`: Version of structure. This value is currently set to 1,
and will be reset if the versioning implementation is incompatibly
We should check it for correctness.

[InstCombine] Fix big-endian miscompile of (bitcast (zext/trunc
Summary: optimizeVectorResize is rewriting patterns like:
%1 = bitcast vector %src to integer
%2 = trunc/zext %1
%dst = bitcast %2 to vector
Since bitcasting between integer an vector types gives different integer
values depending on endianness, we need to take endianness into account.
As it happens the old implementation only produced the correct result
for little endian targets.

[ARM] Remove VHADD patterns
These instructions do not work quite like I expected them to. They
perform the addition and then shift in a higher precision integer, so do
not match up with the patterns that we added.
For example with s8s, adding 100 and 100 should wrap leaving the shift
to work on a negative number. VHADD will instead do the arithmetic in
higher precision, giving 100 overall. The vhadd gives a "better" result,
but not one that matches up with the input.
I am just removing the patterns here. We might be able to re-add them in
the future by checking for wrap flags or changing bitwidths. But for the
moment just remove them to remove the problem cases.
