edge from an index to filesymbols and filesymbols to symbolslabs were named

The current situation/behavior is:
1) llvm-readelf doesn't need a string that is specified by `DT_SONAME`.
2) llvm-readobj/elf always tries to read it, even when there is no `DT_SONAME` tag.
3) Because of that both tools reports a warning for many our test cases.
This patch delays getting a SOName string and changes the behavior (llvm-readobj) to
only report a warning when there is a `DT_SONAME` and a string cab't be read.
Warning is not reported for llvm-readelf, as it never tries to dump it.

The current BufferPlacement transformation contains several concepts for
hoisting allocations. However, more advanced hoisting techniques should not be
integrated into the BufferPlacement transformation. Hence, this CL refactors the
current BufferPlacement pass into three separate pieces: BufferDeallocation and
BufferAllocation(Loop)Hoisting. Moreover, it extends the hoisting functionality
by allowing to move allocations out of loops.

LLVM dialect has been defining Op arguments by deriving the `Arguments` ODS

multiple derivations, and is inconsistent with other ODS files. Use the `let

This patch breaks Orc.h up into Orc.h, LLJIT.h and OrcEE.h.
Orc.h contain core Orc utilities.
LLJIT.h contains LLJIT specific types and functions.
OrcEE.h contains types and functions that depend on ExecutionEngine.
The intent is that these headers should match future library divisions: Clients
who only use Orc.h should only need to link againt the Orc core libraries,
clients using LLJIT.h will also need to link against LLVM core, and clients
using OrcEE.h will also have to link against ExecutionEngine.
In addition to breaking up the Orc.h header this patch introduces functions to:
(1) Set the object linking layer creation function on LLJITBuilder.
(2) Create an RTDyldObjectLinkingLayer instance (particularly for use in (1)).
(3) Register JITEventListeners with an RTDyldObjectLinkingLayer.
Together (1), (2) and (3) can be used to force use of RTDyldObjectLinkingLayer
as the underlying JIT linker for LLJIT, rather than the platform default, and
to register event listeners with the RTDyldObjectLinkingLayer.
C API clients can now define a custom definition generator by providing a
callback function (to implement DefinitionGenerator::tryToGenerate) and context
object. All arguments for the DefinitionGenerator::tryToGenerate method have
been given C API counterparts, and the API allows for optionally asynchronous
generation.
Symbol string pool entries are ref counted, but not automatically cleared.
This can cause the size of the pool to grow without bound if it's not
periodically cleared. These functions allow that to be done via the C API.
This patch moves definition generation out from the session lock, instead
running it under a per-dylib generator lock. It also makes the
DefinitionGenerator::tryToGenerate method optionally asynchronous: Generators
are handed an opaque LookupState object which can be captured to stop/restart
the lookup process.
The new scheme provides the following benefits and guarantees:
(1) Queries that do not need to attempt definition generation (because all
requested symbols matched against existing definitions in the JITDylib)
can proceed without being blocked by any running definition generators.
(2) Definition generators can capture the LookupState to continue their work
asynchronously. This allows generators to run for an arbitrary amount of
time without blocking a thread. Definition generators that do not need to
run asynchronously can return without capturing the LookupState to eliminate
unnecessary recursion and improve lookup performance.
(3) Definition generators still do not need to worry about concurrency or
re-entrance: Since they are still run under a (per-dylib) lock, generators
will never be re-entered concurrently, or given overlapping symbol sets to
generate.
Finally, the new system distinguishes between symbols that are candidates for
generation (generation candidates) and symbols that failed to match for a query
(due to symbol visibility). This fixes a bug where an unresolved symbol could
trigger generation of a duplicate definition for an existing hidden symbol.
