Prepatory patch before changing LibCallSimplifier to use the FMF.
Also, tighten the CHECK lines and give the tests more meaningful names.

Target independent, SSA-based data flow framework for representing
data flow between physical registers.
This commit implements the creation of the actual data flow graph.
llvm-svn: 257477
Summary:
This fixes three bugs, in all of which state is not or incorrecly reset between
objects (i.e. when reusing the same pass manager to create multiple object
files):
1) AttributeSection needs to be reset to nullptr, because otherwise the backend
will try to emit into the old object file's attribute section causing a
segmentation fault.
2) MappingSymbolCounter needs to be reset, otherwise the second object file
will start where the first one left off.
3) The MCStreamer base class resets the Streamer's e_flags settings. Since
EF_ARM_EABI_VER5 is set on streamer creation, we need to set it again
after the MCStreamer was rest.
Also rename Reset (uppser case) to EHReset to avoid confusion with
reset (lower case).

(64 to 128-bit) matches against the pattern fragment 'vzmovl_v2i64'
(a zero-extended 64-bit load).
However, a change in r248784 teaches the instruction combiner that only
the lower 64 bits of the input to a 128-bit vcvtph2ps are used. This means
the instruction combiner will ordinarily optimize away the upper 64-bit
insertelement instruction in the zero-extension and so we no longer select
the memory-register form. To fix this a new pattern has been added.

With this, one can build a lib from the objects of other libs:
set(SOURCES

$<TARGET_OBJECTS:obj.clingMetaProcessor>

handlers.
It is expected that RPC handlers will usually be member functions. Accepting them
directly in handle and expect allows for the remove of a lot of lambdas an
explicit error variables.
This patch also uses this new feature to substantially tidy up the
OrcRemoteTargetServer class.

Since function definitions are not loaded into the address space, PT_LOAD is
inappropriate. PT_WEBASSEMBLY_FUNCTIONS is used to identify where the function
definitions are so that they can be processed at program startup time.

The layering of where the various loop unroll parameters are
initialized and overridden here was very confusing, making it pretty
difficult to tell just how the various sources interacted. Instead, we
put all of the initialization logic together in a single function so
that it's obvious what overrides what.

Function::copyAttributesFrom will copy the personality function, prefix
data and prolog data from the source function to the new function, and
is invoked when the IRMover copies the function prototype. This puts a
reference to a constant in the source module on a function in the dest
module, which causes an error when deleting the source module after
importing, since the personality function in the source module still has
uses (this would presumably also be an issue for the prologue and prefix
data). Remove the copies added to the dest copy when creating the new
prototype, as they are mapped properly when/if we link the function body.

Currently WebAssembly has two kinds of relocations; data addresses and
function addresses. This adds ELF relocations for them, as well as an
MC symbol kind to indicate which type of relocation is needed.

Apparently the preferred version is the incredibly complicated
VerifyVersionInfoW function.
Rename the function to avoid potential future name clashes.

Currently we're unrolling loops more in minsize than in optsize, which
means -Oz will have a larger code size than -Os. That doesn't make any
sense.
This resolves the FIXME about this in LoopUnrollPass and extends the
optsize test to make sure we use the smaller threshold for minsize as
well.

This is a continuation of adding FMF to call instructions:
http://reviews.llvm.org/rL255555
The intent of the patch is to preserve the current behavior of the transform except
that we use the sqrt instruction's 'fast' attribute as a trigger rather than the
function-level attribute.
But this raises a bug noted by the new FIXME comment.
In order to do this transform:
sqrt((x * x) * y) ---> fabs(x) * sqrt(y)
...we need all of the sqrt, the first fmul, and the second fmul to be 'fast'.
If any of those ops is strict, we should bail out.
