We use a simple bump ptr in the `libc` tests. If we run out of data we
can currently return other static memory and have weird failure cases.
We should fail more explicitly here by returning a null pointer instead.

This patch adds the necessary hacks to support global constructors and
destructors. This is an incredibly hacky process caused by the primary
fact that Nvidia does not provide any binary tools and very little
linker support. We first had to emit references to these functions and
their priority in D149451. Then we dig them out of the module once it's
loaded to manually create the list that the linker should have made for
us. This patch also contains a few Nvidia specific hacks, but it passes
the test, albeit with a stack size warning from `ptxas` for the
callback. But this should be fine given the resource usage of a common
test.
This also adds a dependency on LLVM to the NVPTX loader, which hopefully doesn't
cause problems with our CUDA buildbot.
Depends on D149451

The integration tests require the C memory functions as the compiler may
emit calls to them directly. The tests normally use the `__internal__`
variant that is built for testing, but these memory functions were
linked directly to preserve the entrypoint. Instead, we forward delcare
the internal versions and map the entrypoints to them manually inside
the integration test. This allows us to use the internal versions of
these files like the rest of the test objects.

Fixes#61355. The __dso_handle decl was introduced incorrectly into the startup
objects during the integration test cleanup which moved the integration tests
away from using an artificial sysroot to using -nostdlib. Having it in the
startup creates the duplicate symbol error when one does not use -nostdlib.
Since this is an integration test only problem, it is meaningful to keep it in
the integration test anyway.

This part of the effort to make all test related pieces into the `test`
directory. This helps is excluding test related pieces in a straight
forward manner if LLVM_INCLUDE_TESTS is OFF. Future patches will also move
the MPFR wrapper and testutils into the 'test' directory.
