Use std::vector instead of boost::container::small_vector under MSan

There are some issues with dtors in boost::container::small_vector
and/or vector, which is reported by MSan as an error.

The suppression __attribute__((no_sanitize_memory)) works until
clang-15, but since clang-16 it does not. It looks like before clang-16
this no_sanitize_memory works for all child functions, while since
clang-16 only for this function. I've tried to add few others, but a) it
looks icky b) I haven't managed to finish this process.

Also I've measured the performance and it hadn't been changed. Though
boost::small_vector should be faster then std::vector, but apparently my
particular case hadn't affected too much.

And one more thing, MSan reports this only with -O0, with -O3 - it is
not reproduced.

Merge pull request #144 from rschu1ze/rs/fix-libcxx16

Fix compilation with libcxx 16

Fix compilation with libcxx 16

After upgrading our (ClickHouse's) libcxx from 15 to 16, the compiler
started to complain about usage of an incomplete type "RoseInstruction"
in this (header) function:

  void RoseProgram::replace(Iter it, std::unique_ptr<RoseInstruction> ri) {
    ...

The reason is that libcxx 16 is the first version which implements C++23
constexpr std::unique_ptr (P2273R3, see (*)). RoseProgram::replace()
happens to be be const-evaluatable and the compiler tries to run
std::unique_ptr's ctor + dtor. This fails because at this point
RoseInstruction isn't defined yet.

There are two ways of fixing this:
1. Include rose_build_instruction.h (which contains RoseInstruction)
   into rose_build_program.h. Disadvantage: The new include will
   propagate transitively into all callers.
2. Move the function implementation into the source file which sees
   RoseInstruction's definition already. Disadvantage: Template
   instantiation is no longer automatic, instead there must be either a)
   explicit template instantiation (e.g. in rose_build_program.cpp) or
   b) all callers which instantiate the function must live in the same
   source file and do the instantiations by themselves. Fortunately, the
   latter is the case here, but potential future code outside
   rose_build_program.cpp will require ugly explicit instantiation.

Fix segfaults on allocation failure (#4)

Throw std::bad_alloc instead of returning nullptr from
ue2::AlignedAllocator. Allocators for STL containers are expected never
to return with an invalid pointer, and instead must throw on failure.
Violating this expectation can lead to invalid pointer dereferences.

Optimize vectorscan for aarch64 by using shrn instruction

This optimization is based on the thread
https://twitter.com/Danlark1/status/1539344279268691970 and uses
shift right and narrow by 4 instruction https://developer.arm.com/documentation/ddi0596/2020-12/SIMD-FP-Instructions/SHRN--SHRN2--Shift-Right-Narrow--immediate--

To achieve that, I needed to redesign a little movemask into comparemask
and have an additional step towards mask iteration. Our benchmarks
showed 10-15% improvement on average for long matches.

Optimized and correct version of movemask128 for ARM

Closes #99

https://gcc.godbolt.org/z/cTjKqzcvn

Previous version was not correct because movemask thought of having bytes 0xFF. We can fully match the semantics + do it faster with USRA instructions.
