CodeGen: Reduce LValue and CallArgList memory footprint before recommitting r326946

Recent change r326946 (https://reviews.llvm.org/D34367) causes regression in Eigen due to increased
memory footprint of CallArg.

This patch reduces LValue size from 112 to 96 bytes and reduces inline argument count of CallArgList
from 16 to 8.

It has been verified that this will let the added deep AST tree test pass with r326946.

In the long run, CallArg or LValue memory footprint should be further optimized.

[LLVM-C] Redo unnamed_address attribute bindings

Summary:
The old bindings should have used an enum instead of a boolean.  This
deprecates LLVMHasUnnamedAddr and LLVMSetUnnamedAddr , replacing them
with LLVMGetUnnamedAddress and LLVMSetUnnamedAddress respectively that do.
Though it is unlikely LLVM will gain more supported global value linker

The ParseTypes method can be very slow if a program has a long list of compile units containing needed modules. Debugging clang-cl with lldb will show the problem.

6 years ago[PDB] Support dumping injected sources via the DIA reader.

[PDB] Support dumping injected sources via the DIA reader.

Injected sources are basically a way to add actual source file content
to your PDB. Presumably you could use this for shipping your source code
with your debug information, but in practice I can only find this being
used for embedding natvis files inside of PDBs.

In order to effectively test LLVM's natvis file injection, we need a way
to dump the injected sources of a PDB in a way that is authoritative
(i.e. based on Microsoft's understanding of the PDB format, and not
LLVM's). To this end, I've added support for dumping injected sources
via DIA. I made a PDB file that used the /natvis option to generate a
test case.

[lit] - Allow 1 test to report multiple micro-test results to provide support for microbenchmarks.

Summary:
These changes are to allow to a Result object to have nested Result objects in
order to support microbenchmarks. Currently lit is restricted to reporting one
result object for one test, this change provides support tests that want to
report individual timings for individual kernels.

This revision is the result of the discussions in
https://reviews.llvm.org/D32272#794759,
https://reviews.llvm.org/D37421#f8003b27 and https://reviews.llvm.org/D38496.
It is a separation of the changes purposed in https://reviews.llvm.org/D40077.

This change will enable adding LCALS (Livermore Compiler Analysis Loop Suite)
collection of loop kernels to the llvm test suite using the google benchmark
library (https://reviews.llvm.org/D43319) with tracking of individual kernel
timings.

Previously microbenchmarks had been handled by using macros to section groups
of microbenchmarks together and build many executables while still getting a
grouped timing (MultiSource/TSVC). Recently the google benchmark library was
added to the test suite and utilized with a litsupport plugin. However the
limitation of 1 test 1 result limited its use to passing a runtime option to
run only 1 microbenchmark with several hand written tests
(MicroBenchmarks/XRay). This runs the same executable many times with different
hand-written tests. I will update the litsupport plugin to utilize the new
functionality (https://reviews.llvm.org/D43316).

These changes allow lit to report micro test results if desired in order to get
many precise timing results from 1 run of 1 test executable.

[SelectionDAGBuilder] Replace deprecated calls to MemoryIntrinsic::getAlignment() (NFCI)

Summary:
This change is part of step five in the series of changes to remove alignment argument from
memcpy/memmove/memset in favour of alignment attributes. In particular, this changes the
SelectionDAGBuilder to cease using the old getAlignment() API of MemoryIntrinsic in favour of getting
source & dest specific alignments through the new API.

Steps:
Step 1) Remove alignment parameter and create alignment parameter attributes for
memcpy/memmove/memset. ( rL322965, rC322964, rL322963 )
Step 2) Expand the IRBuilder API to allow creation of memcpy/memmove with differing
source and dest alignments. ( rL323597 )
Step 3) Update Clang to use the new IRBuilder API. ( rC323617 )
Step 4) Update Polly to use the new IRBuilder API. ( rL323618 )
Step 5) Update LLVM passes that create memcpy/memmove calls to use the new IRBuilder API,
and those that use use MemIntrinsicInst::[get|set]Alignment() to use [get|set]DestAlignment()
and [get|set]SourceAlignment() instead. ( rL323886, rL323891, rL324148, rL324273, rL324278,
rL324384, rL324395, rL324402, rL324626, rL324642, rL324653, rL324654, rL324773, rL324774,
rL324781, rL324784, rL324955, rL324960, rL325816, rL327398 )
Step 6) Remove the single-alignment IRBuilder API for memcpy/memmove, and the
MemIntrinsicInst::[get|set]Alignment() methods.
