Split the creation of program headers in a few steps.
IMHO this makes the code easier to read and should help with linker
scripts.
This is strongly based on D16575. The main differences are:
We record a range of sections, not every section in a program header.
scanHeaders takes case of deciding what goes in every program header,
including PT_GNU_RELRO
We create dummy sections for the start of the file
With this, program header creation has 3 isolated stages:
Map sections to program headers.
Assign addresses to *sections*
Looking at sections find the address and size of each program header.

Bail on compilation as soon as a job fails.
Previously we attempted to be smart; if one job failed, we'd run all

Problem is, this doesn't work well for e.g. CUDA compilation without
-save-temps. In this case, the device-side and host-side Assemble
actions (which actually are responsible for preprocess, compile,
backend, and assemble, since we're not saving temps) are necessarily
distinct. So our clever heuristic doesn't help us, and we repeat every
error message once for host and once for each device arch.
The main effect of this change, other than fixing CUDA, is that if you

[LVI] Handle constants defensively
There's nothing preventing callers of LVI from asking for lattice values representing a Constant. In fact, given that several callers are walking back through PHI nodes and trying to simplify predicates, such queries are actually quite common. This is mostly harmless today, but we start volatiling assertions if we add new calls to getBlockValue in otherwise reasonable places.
Note that this change is not NFC. Specifically:
1) The result returned through getValueAt will now be more precise. In principle, this could trigger any latent infinite optimization loops in callers, but in practice, we're unlikely to see this.
2) The result returned through getBlockValueAt is potentially weakened for non-constants that were previously queried. With the old code, you had the possibility that a later query might bypass the cache and discover some information the original query did not. I can't find a scenario which actually causes this to happen, but it was in principle possible. On the other hand, this may end up reducing compile time when the same value is queried repeatedly.

Now that SymbolFileDWARF supports having types in completely separate .pcm file with "-fmodules -gmodules", each SymbolFileDWARF can reference module DWARF info by looking in other DWARF files. Then if you have 1000 .o files that each reference one or more .pcm files in their debug info, a simple Module::FindTypes(...) call can end up searching the same .pcm file over and over and over. Now all internal FindTypes methods in classes (ModuleList, Module, SymbolFile) now take an extra argument:
llvm::DenseSet<lldb_private::SymbolFile *> &searched_symbol_files
Each time a SymbolFile::FindTypes() is called, it needs to check the searched_symbol_files list to make sure it hasn't already been asked to find the type and return immediately if it has been checked. This will stop circular dependencies from also crashing LLDB during type queries.

Recommit r260012 - Cleanup node-type handling in the unordered containers.
This time I kept <ext/hash_map> working!
This patch is the first in a series of patches that's meant to better
support unordered_map. unordered_map has a special "value_type" that
differs from pair<const Key, Value>. In order to meet the EmplaceConstructible
and CopyInsertable requirements we need to teach __hash_table about this
special value_type.
This patch creates a "__hash_node_types" traits class that contains
all of the typedefs needed by the unordered containers and it's iterators.
These typedefs include ones for each node type and node pointer type,
as well as special typedefs for "unordered_map"'s value type.
As a result of this change all of the unordered containers now all support
incomplete types.
As a drive-by fix I changed the difference_type in __hash_table to always
be ptrdiff_t. There is a corresponding change to size_type but it cannot
take affect until an ABI break.
This patch will be followed up shortly with fixes for various unordered_map
bugs and problems.

[ThinLTO] Use MD5 hash in function index.
Summary:
This patch uses the lower 64-bits of the MD5 hash of a function name as
a GUID in the function index, instead of storing function names. Any
local functions are first given a global name by prepending the original
source file name. This is the same naming scheme and GUID used by PGO in
the indexed profile format.
This change has a couple of benefits. The primary benefit is size
reduction in the combined index file, for example 483.xalancbmk's
combined index file was reduced by around 70%. It should also result in
memory savings for the index file in memory, as the in-memory map is
also indexed by the hash instead of the string.
Second, this enables integration with indirect call promotion, since the
indirect call profile targets are recorded using the same global naming
convention and hash. This will enable the function importer to easily
locate function summaries for indirect call profile targets to enable
their import and subsequent promotion.
The original source file name is recorded in the bitcode in a new
module-level record for use in the ThinLTO backend pipeline.

[PGO] Differentiate Clang instrumentation and IR level instrumentation profiles
This patch uses one bit in profile version to differentiate Clang
instrumentation and IR level instrumentation profiles.
PGOInstrumenation generates a COMDAT variable __llvm_profile_raw_version so
that the compiler runtime can set the right profile kind.
For Maco-O platform, we generate the variable as linkonce_odr linkage as
COMDAT is not supported.
PGOInstrumenation now checks this bit to make sure it's an IR level
instrumentation profile.

Fix handling of the arm IT instruction in the unwinder
The IT instruction can specify condition code for up to 4 consecutive
instruction and it is used quite often by clang in epilogues causing
an issue when trying to unwind from locations covered by the IT
instruction and for locatins inmediately after the IT instruction.
Changes made to fix it:
* Introduce the concept of conditional instruction block what is a list
of consecutive instructions with the same condition. We update the
unwind information during the conditional instruction block and when
we reach the end of it (first instruction with a differemt condition)
then we restore the unwind information we had before the condition.
* Fix a bug in the ARM instruction emulator where neither PC nor the
ITSTATE was advanced when we reached an instruction what we can't
decode.
After the change we have no regression on android-arm running the
regular test suit and TestStandardUnwind also passes when running it
with clang as the compiler (previously it failed on an IT instruction).

This is an idea to make "thread step-in --target" work for the common
case where you have:
1 -> foo (bar(),
2 baz(),
3 lala());
4
You are sitting on line 1, and want to step into foo, but not bar, baz & lala. Unfortunately
there are line table entries for lines 1-3, and lldb doesn't know anything about the nesting
of statement in these lines. So we'll have to use the user's intelligence... This patch adds:
(lldb) thread step-in -t foo --end-line 4
That tells lldb to keep stepping in till line 4, but stop if you step into foo. I think I would
remember to use this when faced with some of the long gnarly call sequences in lldb. But there
might be ways I haven't thought of to make it more convenient. Jason suggests having "end" as a
special token for --end-line which just means keep going to the end of the function, I really want
to get into this thing...
There should be an SB API and tests, which will come if this seems useful.
