Previously, we had different way to stringize SymbolBody and InputFile
to construct error messages. This patch defines overloaded function
toString() so that we don't need to memorize all these different
function names.
With that change, it is now easy to include demangled names in error
messages. Now, if there is a symbol name conflict, we'll print out
both mangled and demangled names.

This abstracts the code for emitting DWARF binary from the DWARFYAML types into reusable interfaces that could be used by ELF and COFF.

Summary:
The test `XRay-aarch64-linux::patching-unpatching.cc` sometimes passes, sometimes fails on buildbots.
This patch disables test `patching-unpatching.cc` for AArch64 targets.

The fix committed in r288851 doesn't cover all the cases.
In particular, if we have an instruction with side effects
which has a no non-dbg use not depending on the bits, we still
perform RAUW destroying the dbg.value's first argument.
Prevent metadata from being replaced here to avoid the issue.

ConstantExpr instances were emitting code into the current block rather than
the entry block. This meant they didn't necessarily dominate all uses, which is
clearly wrong.

Since DWARF formatting is agnostic to the object file it is stored in, it doesn't make sense for this to be in the MachOYAML implementation. Pulling it into its own namespace means we could modify the ELF and COFF YAML tools to emit DWARF as well.
In a follow-up patch I will better abstract this in obj2yaml and yaml2obj so that the DWARF bits in the tools can be re-used too.

Having to ask the MIRBuilder for the current function is a little awkward, and
I'm intending to improve how that's threaded through anyway.
llvm-svn: 288983
MachineIRBuilder had weird before/after and beginning/end flags for the insert
point. Unfortunately the non-default means that instructions will be inserted
in reverse order which is almost never what anyone wants.
Really, I think we just want (like IRBuilder has) the ability to insert at any
C++ iterator-style point (i.e. before any instruction or before MBB.end()). So
this fixes MIRBuilders to behave like IRBuilders in this respect.

Currently LLD prints basename of source file name in error messages,
for example:
$ mkdir foo
$ echo 'void _start(void) { foobar(); }' > foo/bar.c
$ gcc -g -c foo/bar.c
$ bin/ld.lld -o out bar.o
bin/ld.lld: error: bar.c:1: undefined symbol 'foobar'
$
This should say:
bin/ld.lld: error: foo/bar.c:1: undefined symbol 'foobar'

If we don't skip over DEBUG_VALUEs, we get differences between -g and non-g
code.
This fixes PR31242.

The second operand of an "ri" instruction may be an immediate, but it may
also be a globalvariable, so we should make any assumptions.
This fixes PR31271.

* __host__ __device__ functions are no longer considered to be
redeclarations of __host__ or __device__ functions. This prevents
unintentional merging of target attributes across them.
* Function target attributes are not considered (and must match) during
explicit instantiation and specialization of function templates.

The tests that already work are folded in InstSimplify, so those
tests should be redundant and we can remove them if they don't
seem worthwhile for completeness.

Summary: Since CLZ is not available for Thumb1, we use __ARM_ARCH_ISA_THUMB != 1 as one of the conditions.

Add and implement foreachElt for isl_map, isl_set and isl_union_set. These are
used by an out-of-tree patch which is in process of being upstreamed.

This patch refactor how to apply the R_AARCH64_LDST{8,16,32,64,128}_ABS_NC
relocations by adding a new function to correct extract the bits expected
by each relocation. This make is explicit which are the bits range expected
and simplify the code to mask and shift the deriable values.
It also fixes the R_AARCH64_LDST128_ABS_LO12_NC mask, although in pratice
the mask/shift always returns a 16 bytes aligned value.
Checked on AArch64 and with test-suite.
