Summary: The thread_start function in libc doesn't contain any epilogue and prologue instructions. Hence unwinding fail when we are stopped in thread_start.

Tag and specifier printing can be suppressed in Decl::printGroup, but these suppressions leak into the initializers. Thus
int *x = ((void *)0), *y = ((void *)0);
gets printed as
int *x = ((void *)0), *y = ((*)0);
And
struct { struct Z z; } z = {(struct Z){}};
gets printed as
struct { struct Z z; } z = {(){}};
The stops the suppressions from leaking into the initializers.

This was originally committed as r255762, but reverted as it broke windows
bots. Re-commitiing the exact same patch, as the underlying cause was fixed by
r258677.
ARMv8.2-A adds 16-bit floating point versions of all existing VFP
floating-point instructions. This is an optional extension, so all of
these instructions require the FeatureFullFP16 subtarget feature.
The assembly for these instructions uses S registers (AArch32 does not
have H registers), but the instructions have ".f16" type specifiers
rather than ".f32" or ".f64". The top 16 bits of each source register
are ignored, and the top 16 bits of the destination register are set to
zero.
These instructions are mostly the same as the 32- and 64-bit versions,
but they use coprocessor 9 rather than 10 and 11.
Two new instructions, VMOVX and VINS, have been added to allow packing
and extracting two 16-bit floats stored in the top and bottom halves of
an S register.
New fixup kinds have been added for the PC-relative load and store
instructions, but no ELF relocations have been added as they have a
range of 512 bytes.

This is a fix for https://llvm.org/bugs/show_bug.cgi?id=22796.
The previous implementation of ClassInfo::operator< allowed cycles of classes
such that x < y < z < x, meaning that a list of them cannot be correctly
sorted, and the sort order could differ with different standard libraries.
The original implementation sorted classes by ValueName if they were otherwise
equal. This isn't strictly necessary, but some backends seem to accidentally
rely on it. If I reverse this comparison I get 8 test failures spread across
the AArch64, Mips and X86 backends, so I have left it in until those backends
can be fixed.
There was one case in the X86 backend where the observable behaviour of the
assembler is changed by this patch. This was because some of the memory asm
operands were not marked as children of X86MemAsmOperand.

The ORC ObjectLinkingLayer uses this flag during symbol lookup. Failure to set
it causes all symbols to behave as if they were non-exported, which has caused
failures in the kaleidoscope tutorials on Windows. Raising the flag should
un-break the tutorials.
No test case yet - none of the existing command line tools for printing symbol
tables (llvm-nm, llvm-objdump) show the status of this flag, and I don't want to
change the format from these tools without consulting their owners. I'll send an
email to the dev-list to figure out the right way forward.

A cleanup can have paths which unwind or end up in unreachable.
If there is an unreachable path *and* a path which unwinds to caller,
we would mistakenly inject an unwind path to a catchswitch on the
unreachable path. This results in a verifier assertion firing because
the cleanup unwinds to two different places: to the caller and to the
catchswitch.
This occured because we used getCleanupRetUnwindDest to determine if the
cleanuppad had no cleanuprets.
This is incorrect, getCleanupRetUnwindDest returns null for cleanuprets
which unwind to caller.
