PR25763 demonstrated an issue with D14683 - vector comparison constant folding only works for i1 results, so we need to split off the sign-extension of the result to the required type. Luckily this can be done with the existing type legalization code.

check_memcpy test added in r254959 fails on some configurations due to
memcpy() calls inserted by Clang. Try harder to avoid them by using
internal_memcpy() where applicable.

When llvm-lit prints a failure, you'll see something like 'lld *command*' However, you can't then take this, paste it in to a terminal and run it, because it's not got the absolute path of lld.
llvm and clang's lit.cfg files contain lists of commands to look for which are substituted by their full paths. So now you'd see something like '*build dir*/bin/lld *command*'.
This patch adds the same capability to lld's lit.cfg

The delta64 relocation is represented as the pair ARM64_RELOC_SUBTRACTOR and ARM64_RELOC_UNSIGNED.
Those should always have the same offset, so this adds a check and tests to ensure this is the case.
Also updated the error printing in this case to shows both relocs when erroring on pair.

InstrProfiling.h file declares profile runtime public APIs.
It has become a dumping place for many different things, which
needs cleanups. In this change, core type declarations and
portability macros are moved to a new file InstrProfilingPort.h.

Avoid O(N^2) behaviour when checking for bad bitcasts in `ConstantExpr`s
buried inside of aggregate initializers to `GlobalVariable`s. I've:
- centralized the "visited" set for recursing through `ConstantExpr`s so
that expressions are only visited once per Verifier run,
- removed the duplicate logic for the stack visit, and
- avoided recursing into other `GlobalValue`s.
This recovers roughly a 100x time difference in clang compiles of a
particular input file (filled with large cross-referencing tables) that
depends on whether `-disable-llvm-verifier` is on. This slowdown was
caused by r187506, which introduced these checks.
Now, avoiding `-disable-llvm-verifier` only causes a 2x slowdown for
this case.
(Interestingly, dumping the textual IR for this file starts at least
50GB of global variable initializers (I don't know the total, since I
killed the dump)...)

Summary:
Adds support for in-memory round-trip of sample profile data along with basic
round trip unit tests. This will also make it easier to include unit tests for
future changes to sample profiling.

This is a redo of r255137 (reverted at r255227) which was a redo of
r255124 (reverted at r255126) with a fixed check for a scalar source
type and an added test for the failure that caused the revert.
Original commit message:
Example:
bitcast (extractelement (bitcast <2 x float> %X to <2 x i32>), 1) to float
--->
extractelement <2 x float> %X, i32 1
This is part of fixing PR25543:
https://llvm.org/bugs/show_bug.cgi?id=25543
The next step will be to generalize this fold:
trunc ( lshr ( bitcast X) ) -> extractelement (X)
Ie, I'm hoping to replace the existing transform of:
bitcast ( trunc ( lshr ( bitcast X)))
added by:
http://reviews.llvm.org/rL112232
with 2 less specific transforms to catch the case in the bug report.

Adding the modules to the global module list eleminate issues in the
case when a module is unloaded from the target but some object (e.g.
breakpoint) still referencing them with weak pointers. It also speeds
up the case when we load, unload, load the same shared library because
the global module cache will keep the parsed debug info around between
the 2 load (this scenario happens for some code on android).

A linker normally has two stages: symbol resolution and "moving stuff".
In lib/Linker there is the complication of lazy linking some globals,
but it was still far more mixed than it needed to.
This splits the linker into a lower level IRMover and the linker proper.
The IRMover just takes a list of globals to move and a callback that
lets the user control what is lazy linked.
The main motivation is that now tools/gold (and soon lld) can use their
own symbol resolution to instruct IRMover what to do.

We extend the search for redundant stores to predecessor blocks that
unconditionally lead to the block BB with the current store instruction. That
also includes single-block loops that unconditionally lead to BB, and
if-then-else blocks where then- and else-blocks unconditionally lead to BB.

LLVM IR frequently contains bitcast operations between floating point and
integer values of the same width. Doing this through memory operations is
quite expensive on PPC. This patch allows the use of direct register moves
between FPRs and GPRs for lowering bitcasts.
