[Reassociate] Skip analysis of dead code to avoid infinite loop.
Summary:
It was detected that the reassociate pass could enter an inifite
loop when analysing dead code. Simply skipping to analyse basic
blocks that are dead avoids such problems (and as a side effect
we avoid spending time on optimising dead code).
The solution is using the same Reverse Post Order ordering of the
basic blocks when doing the optimisations, as when building the
precalculated rank map. A nice side-effect of this solution is
that we now know that we only try to do optimisations for blocks
with ranked instructions.

- Indicate to the log handler function being called that this is a

This fixes a bug that is a result of not saving enough of the register

used by the function being tail-exited into manifesting as runtime

Fix __libcpp_is_constructible for source types with explicit conversion operators.
Previously __libcpp_is_constructible checked the validity of reference
construction using 'eat<To>(declval<From>())' but this doesn't consider
From's explicit conversion operators. This patch teaches __libcpp_is_constructible
how to handle these cases. To do this we need to check the validity
using 'static_cast<To>(declval<From>())'. Unfortunately static_cast allows
additional base-to-derived and lvalue-to-rvalue conversions, which have to be
checked for and manually rejected.
While implementing these changes I discovered that Clang incorrectly
rejects `static_cast<int&&>(declval<float&>())` even though
`int &&X(declval<float&>())` is well formed. In order to tolerate this bug
the `__eat<T>(...)` needs to be left in-place. Otherwise it could be replaced
entirely with the new static_cast implementation.

equal to SHN_LORESERVE (0xff00), this member has the value SHN_XINDEX
(0xffff) and the actual index of the section name string table section
is contained in the sh_link field of the section header at index 0.
---------------------------
So we only have to check for it being SHN_XINDEX. Also, sh_link is
always 32 bits, so don't return an uintX_t.

[test] Fix detecting LLVM zlib support in stand-alone builds
Fix the test run to declare missing HAVE_LIBZ value in stand-alone
builds, using the LLVM_ENABLE_ZLIB that is exported in LLVMConfig.cmake.
When using in-tree builds, HAVE_LIBZ is declared in
cmake/config-ix.cmake as a result of LLVM's CMake checks. When building
stand-alone, this value is not available and as a result caused clang to
wrongly assume that LLVM was built without zlib support.
To fix it, set it to the value of LLVM_ENABLE_ZLIB. While this variable
is originally used to control the user preference, LLVM updates its
value to 0 if zlib checks fail. Therefore, we can use it to reliably
determine whether LLVM was built with zlib support or not.

[ELF/GC] Fix pending references to garbage collected sections.
The example reported in PR30793 shows a case where gc reclaims
a SHF_TLS section, but it doesn't reclaim the section containing
the debug info for it.
This is expected, as we do not reclaim non-alloc sections
during the garbage collection phase (and this is not going to
change anytime soon, at least this is what I gathered last I
talked with Rafael about it).
So, we end up with a pending reference, thinking that the input
was invalid (which is not true, as it's GC that removed the
SHT_TLS section, and therefore didn't create the PT_TLS *segment*
for it). In cases like this, just assign a VA of zero at relocation
time instead of error'ing out (this is what gold does as well, FWIW).
