[asan] Re-exec without ASLR if needed on 64-bit Linux (#132682)
This generalizes https://github.com/llvm/llvm-project/pull/131975 to non-32-bit Linux (i.e., 64-bit Linux).
This works around an edge case in 64-bit Linux, whereby the memory layout is incompatible if the stack size is unlimited AND ASLR entropy is 31+ bits (see https://github.com/google/sanitizers/issues/856#issuecomment-2747076811).
More generally, this "re-exec without ASLR if layout is incompatible" is a hammer that can work around most shadow mapping issues, without incurring the overhead of using a dynamic shadow.
