Convert the ObjCDeallocChecker to be path sensitive. The primary
motivation for this change is to prevent false positives when -dealloc calls
helper invalidation methods to release instance variables, but it additionally
improves precision when -dealloc contains control flow. It also reduces the need
for pattern matching. The check for missing -dealloc methods remains AST-based.

ELF: Implement ICF.
This patch implements the same algorithm as LLD/COFF's ICF. I'm
not going to repeat the same description about how it works, so you
want to read the comment in ICF.cpp in this patch if you want to know
the details. This algorithm should be more powerful than the ICF
algorithm implemented in GNU gold. It can even merge mutually-recursive
functions (which is harder than one might think).
ICF is a fairly effective size optimization. Here are some examples.
LLD: 37.14 MB -> 35.80 MB (-3.6%)
Clang: 59.41 MB -> 57.80 MB (-2.7%)
The lacking feature is "safe" version of ICF. This merges all
identical sections. That is not compatible with a C/C++ language
requirement that two distinct functions must have distinct addresses.
But as long as your program do not rely on the pointer equality
(which is in many cases true), your program should work with the
feature. LLD works fine for example.
GNU gold implements so-called "safe ICF" that identifies functions
that are safe to merge by heuristics -- for example, gold thinks
that constructors are safe to merge because there is no way to
take an address of a constructor in C++. We have a different idea
which David Majnemer suggested that we add NOPs at beginning of
merged functions so that two or more pointers can have distinct
values. We can do whichever we want, but this patch does not
include neither.

[PM] Add the IR unit type to the pass manager's logging and make all of
the testing more more explicit.
This will currently fail on platforms without support for getTypeName.
While an assert failure seems too harsh, I'm hoping we're OK with the
regression test failure, and I'd like to find out about what platforms
actually exist in this state if there are any so we can get
implementations in place for them.
But if we just can't fix all the host compilers to have a reasonably
portable variant of getTypeName and are worried about xfailing this test
on those platforms, I can add the horrible regular expression magic to
make the tests support "unknown" here as well.

Twek fix for PR24473 (r261506) - Preserve the template arguments as written
(within the DeclRefExpr Node) when creating AST nodes that reference specializations of static data member templates. While we pass the template args through for all non-instance members, they should only be relevant (i.e. non-null) for variable template ids (assertion added for that assumption)
Also preserve the FoundDecl that refers to the canonical Decl (the primary VarTemplateDecl for a variable template specialization) that we are referencing in our DeclRefExpr. Not sure why this was not being done for non-variable template-ids.
No functionality change - so no tests added.

[ELF][MIPS] Enumerate absolute MIPS relocations in the isRelRelative
This commit does two related thing. At first, it enumerates supported
absolute MIPS relocations in the `MipsTargetInfo<ELFT>::isRelRelative`
method. In that case the code is shorter and the case switch does not
tend to grow. At second, it prevents R_MIPS_COPY and PLT creation for
relative relocations. For almost all relative MIPS relocations like
R_MIPS_PC19_S2, R_MIPS_PCHI16 etc it does not have a sence. The only
exception is R_MIPS_PC32. GNU linker creates a copy relocation or PLT
entry for it. But I could not find any real test case uses R_MIPS_PC32
with DSO defined symbol as a target. So for now I prefer to skip this
case to simplify the LLD code.

[Support] Add a fancy helper function to get a static name for a type.
This extracts the type name from __PRETTY_FUNCTION__ for compilers that
support it (I've opted Clang, GCC, and ICC into this as I've tested that
they work) and from __FUNCSIG__ which is very similar on MSVC. The
routine falls back gracefully on a stub "UNKNOWN_TYPE" string with
compilers or formats it doesn't understand.
This should be enough for a lot of common cases in LLVM where the real
goal is just to log or print a type name as a debugging aid, and save
a ton of boilerplate in the process. Notably, I'm planning to use this
to remove all the getName() boiler plate from the new pass manager.
The design and implementation is based on a bunch of advice and
discussion with Richard Smith and experimenting with most versions of
Clang and GCC. David Majnemer also provided excellent advice on how best
to do this with MSVC. Richard also checked that ICC does something
reasonable and I'll watch the build bots for other compilers. It'd be
great if someone could contribute logic for xlC and/or other toolchains.
