DwarfDebug: emit type units immediately.
Rather than storing type units in a vector and emitting them at the end
of code generation, emit them immediately and destroy them, reclaiming the
memory we were using for their DIEs.
In one benchmark carried out against Chromium's 50 largest (by bitcode
file size) translation units, total peak memory consumption with type units
decreased by median 17%, or by 7% when compared against disabling type units.
Tested using check-{llvm,clang}, the GDB 7.5 test suite (with
'-fdebug-types-section') and by eyeballing llvm-dwarfdump output on those
Chromium translation units with split DWARF both disabled and enabled, and
verifying that the only changes were to addresses and abbreviation ordering.

[CMake] Produce an empty library for GlobalISel when not building it.
The rational for this change is that LLVMBuild cannot express conditional
dependencies. Therefore, when we start optionally using GlobalISel library for
say AArch64, without that change, all the tools that use the AArch64 library
would need to explicitly link with GlobalISel when we ask for it.
This does not scale.
Instead, we will set the dependencies between the target and GlobalISel and if
we did not ask to build GlobalISel, the library will just be empty.

If two definitions write to independent subregisters then they can be

This is a modified version of a patch proposed (two years ago) by
Vincent Lejeune! This version does not touch the read-undef flags and is
extended for the case of moving a subregister def behind all uses - this
can happen for subregister defs that are completely unused.

[GlobalISel] Add a type to MachineInstr.
We actually need that information only for generic instructions, therefore it
would be nice not to have to pay the extra memory consumption for all
instructions. Especially because a typed non-generic instruction does not make
sense.
The question is then, is it possible to have that information in a union or
something?
My initial thought was that we could have a derived class GenericMachineInstr
with additional information, but in practice it makes little to no sense since
generic MachineInstrs are likely turned into non-generic ones by just switching
the opcode. In other words, we don't want to go through the process of creating
a new, non-generic MachineInstr, object each time we do this switch. The memory
benefit probably is not worth the extra compile time.
Another option would be to keep the type of the MachineInstr in a side table.
This would induce an extra indirection though.
Anyway, I will file a PR to discuss about it and remember we need to come back
to it at some point.

[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.

[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.

a PatFrag. If you want to create a PatFrag on a commutative node
with a hasOneUse predicate, this enables you to specify that the
PatFrag is also commutable.
