Hans Wennborg f6892eda24 [CMake] don't build libLTO when LLVM_ENABLE_PIC is OFF
When cmake is run with -DLLVM_ENABLE_PIC=OFF, build fails while
linking shared library libLTO.so, because its dependencies are built
with -fno-PIC. More details here: https://llvm.org/bugs/show_bug.cgi?id=26484.
This diff reverts r252652 (git 9fd4377ddb83aee3c049dc8757e7771edbb8ee71),
which removed check NOT LLVM_ENABLE_PIC before disabling build for libLTO.so.

Mike Aizatsky 95149921b2 [sancov] improved object files handling.
Multi-dso programs result in multiple coverage files dumped of the form
'<module_name>.<pid>.sancov'. When analyzing these coverage files it is
important to use correct corresponding object file.

This change removes the "-obj" sancov flag and lets user specify object
file names alongside coverage files. Sancov tool would match them using
<module_name> part of coverage file and short file name of the object
file.

Quentin Colombet bde158cbc7 [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.

Thanks to Chris Bieneman and Mehdi Animi for the idea.

Teresa Johnson e1164de5d0 Restore "[ThinLTO] Use MD5 hash in function index." with fix
This restores commit r260408, along with a fix for a bot failure.

The bot failure was caused by dereferencing a unique_ptr in the same
call instruction parameter list where it was passed via std::move.
Apparently due to luck this was not exposed when I built the compiler
with clang, only with gcc.

Teresa Johnson 0919a84071 [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.

Rong Xu 33c76c0cc2 [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.

The patch was submitted as r260164 but reverted due to a Darwin test breakage.

Lang Hames 4f8194e81d [Orc] Add lazy-JITting support for i386.
This patch adds a new class, OrcI386, which contains the hooks needed to
support lazy-JITing on i386 (currently only for Pentium 2 or above, as the JIT
re-entry code uses the FXSAVE/FXRSTOR instructions).

Support for i386 is enabled in the LLI lazy JIT and the Orc C API, and
regression and unit tests are enabled for this architecture.
