AllCallbacks is currently only used to call onStartOfTranslationUnit and
onEndOfTranslationUnit on them. In this (and any other scenario I can
come up with), it is important (or at least better) not to have
duplicates in this container. E.g. currently onEndOfTranslationUnit is
called repeatedly on the same callback for every matcher that is
registered with it.

If a string contained characters outside the ASCII range, lldb-mi would
print them as hexadecimal codes. This patch fixes this behaviour by
converting to UTF-8 instead, by having lldb-mi use registered type
summary providers, when they are available. This patch also fixes
incorrect evaluation of some composite types, like std::string, by
having them use a type registered type summary provider.

Summary:
This adds some more routines to `IRBuilder` around creating calls and
invokes to `gc.statepoint`. These will be used later.

Summary:
This is necessary to keep the cloner from making bogus copies of debug
metadata attached to the IR it is cloning.
Also, avoid running RemapInstruction over all instructions in the common
case that no cloning was performed.

Previously, output sections that are handled specially by the linker
(e.g. PLT or GOT) were created by Writer and passed to other classes
that need them. The problem was that because these special sections
are required by so many classes, the plumbing work became too much
burden.
This patch is to simply make them accessible from anywhere in the
linker to eliminate the plumbing work once and for all.

Introduce the notion of Language-based formatter prefix/suffix
This is meant for languages that share certain data types but present them in syntatically different ways, such that LLDB can now have language-based awareness of which of the syntax variations it has to present to the user when formatting those values
This is goodness for new languages and interoperability, but is NFC for existing languages. As such, existing tests cover this

This reverts commit r249528 and reapply r249431. The fix for the
fallout has been commited in r249575.

There was an off-by-one bug in ip2state tables which manifested when one
call immediately preceded the try-range of the next. The return address
of the previous call would appear to be within the try range of the next
scope, resulting in extra destructors or catches running.
We also computed the wrong offset for catch parameter stack objects. The
offset should be from RSP, not from RBP.

Summary:
After r249211, SCEV can see through some LCSSA phis. Add a
`replacementPreservesLCSSAForm` check before replacing uses of these phi
nodes with a simplified use of the induction variable to avoid breaking
LCSSA.
Fixes 25047.
Depends on D13460.

I'll be using the function in a similar combine for AArch64. The helper was
also improved to handle undef values.

The ARM RTABI defines the half- to single-precision float conversion functions
with an __aeabi prefix, but libgcc only has them with a __gnu prefix. Therefore
we need to emit the __aeabi version when compiling with an eabi or eabihf
triple, and the __gnu version with a gnueabi or gnueabihf triple.

Summary:
This removes all uses of virtual on functions
where override could be used, including on destructors.
It also adds override where virtual was previously
missing.

Summary:
The StackUsesFrames and FunctionCallsChangeCFA virtual functions
aren't used anywhere and aren't overridden by anything.
They were introduced when the ABISysV_ppc* code was added and weren't
used at the time. The review for the commit that added them can be
found at http://reviews.llvm.org/D5988
The commit comment notes that backtraces don't yet work:
Backtraces don't work. This is due to PowerPC ABI using a
backchain pointer in memory, instead of a dedicated frame
pointer register for the backchain.
So there is a possibility these were added with the intent of using
them in the future.

I knee-jerk tried to fix this in completely the wrong way - it's not an
CPU limitation, but an OS/object file type one, so moving it
into a CPU-specific classification didn't help at all.

TokenAnnotator::spaceRequiredBetween was handling TT_ForEachMacro but
not TT_ObjCForIn, so lines that look like:

would incorrectly turn into:

aligning assignments.
This was done correctly when aligning the declarations, but not when
aligning assignments.
FIXME: The code between assignments and declarations alignment is
roughly duplicated and
would benefit from factorization.

When generating an executable or shared library, mark it to tell the dynamic linker to resolve all symbols when the program is started, or when the shared library is linked to using dlopen, instead of deferring function call resolution to the point when the function is first called.
