function and also hooked up better error reporting for when things fail.
Fixed issues with trying to display children of pointers when none are
supposed to be shown (no children for function pointers, and more like this).
This was causing child value objects to be made that were correctly firing
an assertion.

a non-mangled function - we pass the non mangled string down through abi::__cxa_demangle and it
crashes. Usually passing non mangled strings to abi::__cxa_demangle works out fine but not
always, apparently.

within the class. Teach IR gen to look for function definitions in record
lexical contexts when deciding whether to emit a function whose address
was taken. Fixes PR8789.

whether the expression contains an unexpanded parameter pack, in the
same vein as the changes to the Type hierarchy. Compute this bit
within all of the Expr subclasses.
This change required a bunch of reshuffling of dependency
calculations, mainly to consolidate them inside the constructors and
to fuse multiple loops that iterate over arguments to determine type
dependence, value dependence, and (now) containment of unexpanded
parameter packs.
Again, testing is painfully sparse, because all of the diagnostics
will change and it is more important to test the to-be-written visitor
that collects unexpanded parameter packs.

o "output1.txt" for test_pass_host_env_vars() test case
o "output2.txt" for test_run_args_and_env_vars_with_dsym() test case
o "output2.txt" for test_run_args_and_env_vars_with_dwarf() test case
and add teardown hook to test_pass_host_env_vars() in order to properly
unset the host environment variables set while running the test case.

ALso add a teardown hook to the LoadUnloadTestCase.test_dyld_library_path()
test case to have it restore the DYLD_LIBRARY_PATH environment variable.

registers that alias Reg, including itself. This is almost the same as the
existing getAliasSet() method, except for the inclusion of Reg.
The name matches the reflexive TRI::regsOverlap(x, y) relation.
It is very common to do stuff to a register and all its aliases:
stuff(Reg)
for (const unsigned *Alias = TRI->getAliasSet(Reg); *Alias; ++Alias)
stuff(*Alias);
That can now be written as the simpler:
for (const unsigned *Alias = TRI->getOverlaps(Reg); *Alias; ++Alias)
stuff(*Alias);
This change requires a bit more constant space for the alias lists because Reg
is included and because the empty alias list cannot be shared any longer.
If the getAliasSet method is eventually removed, this space can be reclaimed by
sharing overlap lists. For instance, %rax and %eax have identical overlap sets.

linked with a dylib which has been relocated by specifying the DYLD_LIBRARY_PATH environment

regB = move RCX
regA = op regB, regC
RAX = move regA
where both regB and regC are killed. If regB is constrainted to non-compatible
physical registers but regC is not constrainted at all, then it's better to
commute the instruction.
