Add support mips64(el)-linux-gnuabin32 triples, and set them to N32.
Debian architecture name mipsn32/mipsn32el are also added. Set
UseIntegratedAssembler for N32 if we can detect it.

Create a temporary file in the system temporary directory instead of creating a
file in the current directory, which may be not writable. (Fix for an issue
introduced in r342283.)

Before this fix, multiple invocations of testRoundTrip will create multiple
writers which share the same file as output destination. That could introduce
filesystem race issue when multiple subtests are executed concurrently. This
patch assign writers with different files as their output destinations.

The patch saves a function offset table which maps function name index to the
offset of its function profile to the start of the binary profile. By using
the function offset table, for those function profiles which will not be used
when compiling a module, the profile reader does't have to read them. For
profile size around 10~20M, it saves ~10% compile time.

Using llvm::getInputFileDirectory() in unit tests is discouraged, so require an explicit opt-in.
This way, cmake also writes ~60 fewer unused files to disk.

Summary:
The hash computed for an ArrayType was different when first constructed
versus when later profiled due to the constructor default argument, and
we were not tracking constructor / destructor variant as part of the
mangled name AST, leading to incorrect equivalences.

construction, a new convenience lookup method, and add-to layer methods.
ExecutionSession now creates a special 'main' JITDylib upon construction. All
subsequently created JITDylibs are added to the main JITDylib's search order by
default (controlled by the AddToMainDylibSearchOrder parameter to
ExecutionSession::createDylib). The main JITDylib's search order will be used in
the future to properly handle cross-JITDylib weak symbols, with the first
definition in this search order selected.
This commit also adds a new ExecutionSession::lookup convenience method that
performs a blocking lookup using the main JITDylib's search order, as this will
be a very common operation for clients.
Finally, new convenience overloads of IRLayer and ObjectLayer's add methods are
introduced that add the given program representations to the main dylib, which
is likely to be the common case.

The previous implementation traversed all loop blocks and bailed if one
was not a latch block. Since we are only interested in latch blocks, we

Summary:
In this change, we implement a `BlockPrinter` which orders records in a
Block that's been indexed by the `BlockIndexer`. This is used in the
`llvm-xray fdr-dump` tool which ties together the various types and
utilities we've been working on, to allow for inspection of XRay FDR
mode traces both with and without verification.
This change is the final step of the refactoring of D50441.

Summary:
End goal is to update MemorySSA in all loop passes. LoopUnswitch clones all blocks in a loop. SimpleLoopUnswitch clones some blocks. LoopRotate clones some instructions.
Some of these loop passes also make CFG changes.
This is an API based on what I found needed in LoopUnswitch, SimpleLoopUnswitch, LoopRotate, LoopInstSimplify, LoopSimplifyCFG.
Adding dependent patches using this API for context.

Summary:
This patch implements a `BlockVerifier` type which enforces the
invariants of the log structure of FDR mode logs on a per-block basis.
This ensures that the data we encounter from an FDR mode log
semantically correct (i.e. that records follow the documented "grammar"
for FDR mode log records).
This is another part of the refactoring of D50441.
This is a slightly modified version of rL341628, avoiding the
`std::tuple<...>` constructor that is not constexpr in C++11.

The existing memory manager API can not be shared between objects when linking
concurrently (since there is no way to know which concurrent allocations were
performed on behalf of which object, and hence which allocations would be safe
to finalize when finalizeMemory is called). For now, we can work around this by
requiring a new memory manager for each object.
This change only affects the concurrent version of the ORC APIs.
llvm-svn: 341579
Summary:
This change adds a `BlockIndexer` type which maintains pointers to
records that belong to the same process+thread pairs. The indexing
happens with order of appearance of records as they are visited.
This version of the indexer currently only supports FDR version 3 logs,
which contain `BufferExtent` records. We will add support for v2 and v1
logs in follow-up patches.
This is another part of D50441.

The way DIA SDK works is that when you request a symbol, it
gets assigned an internal identifier that is unique for the
life of the session. You can then use this identifier to
get back the same symbol, with all of the same internal state
that it had before, even if you "destroyed" the original
copy of the object you had.
This didn't work properly in our native implementation, and
if you destroyed an object for a particular symbol, then
requested the same symbol again, it would get assigned a new
ID and you'd get a fresh copy of the object. In order to fix
this some refactoring had to happen to properly reuse cached
objects. Some unittests are added to verify that symbol
reuse is taking place, making use of the new unittest input
feature.
llvm-svn: 341503
Occasionally it is useful to have unittest which take inputs.
While we normally try to have this test be more of a lit test
we occasionally don't have tools that can exercise the code
in the right way to test certain things. LLDB has been using
this style of unit test for a while, particularly with regards
to how it tests core dump and minidump file parsing. Recently
i needed this as well for the case where we want to test that
some of the PDB reading code works correctly. It needs to
exercise the code in a way that is not covered by any dumper
and would be impractical to implement in one of the dumpers,
but requires a valid PDB file. Since this is now needed by
more than one project, it makes sense to have this be a
generally supported thing that unit tests can do, and we just
encourage people to use this sparingly.

Summary:
This change adds a `RecordPrinter` type which does some basic text
serialization of the FDR record instances. This is one component of the
tool we're building to dump the records from an FDR mode log as-is.
