the linker script. The cycle in the ELF/LinkerScript.cpp:assignAddresses()
routine will be used to go through all the sections and set all the
addresses correctly.
Add new test to check this case.

Previously, specifying -post-RA-scheduler=true had the side effect of
disabling the antidependency breaker, yielding different behavior than
if the post-RA-scheduler was enabled via the scheduling model.

Actually it is just because D20273 not yet commited, but these 2 were crossing with each other,
and I`ll better find the way to land them separatelly soon.
Initial commit message:
[llvm-mc] - Teach llvm-mc to generate compressed debug sections in zlib style.
Before this patch llvm-mc generated zlib-gnu styled sections.
That means no SHF_COMPRESSED flag was set, magic 'zlib' signature
was used in combination with full size field. Sections were renamed to "*.z*".
This patch reimplements the compression style to zlib one as zlib-gnu looks
to be depricated everywhere.

There are at least 2 places (DAGCombiner, X86ISelLowering) where this could be used instead
of ad-hoc and watered down code that is trying to match a power-of-2 pattern.

This patch changes the order in which we attempt to prove the independence of
strided accesses. We previously did this after we knew the dependence distance
was positive. With this change, we check for independence before handling the
negative distance case. The patch prevents LAA from reporting forward
dependences for independent strided accesses.
This change was requested in the review of D19984.

We're missing interceptors for dispatch_after and dispatch_after_f. Let's add them to avoid false positives. Added a test case.

All additional include directories are relative to the toolchain install
folder. So let's do not pass this folder to each callback to simplify
and slightly reduce the code.

CodeSourcery toolchain is a standalone toolchain which always uses
the same triple name in its paths. It is independent from target
triple used by the driver.

Mask0Imm and ~Mask1Imm must be equivalent and one of the MaskImms is a shifted
mask (e.g., 0x000ffff0). Both 'and's must have a single use.
This changes code like:
and w8, w0, #0xffff000f
and w9, w1, #0x0000fff0
orr w0, w9, w8
into
lsr w8, w1, #4
bfi w0, w8, #4, #12

Summary: One of the cases handled by ValueObjectChild::UpdateValue() uses the entire width of the parent's scalar value as the size of the child, and extracts the child by calling Scalar::ExtractBitfield(). This seems valid but APInt::trunc(), APInt::sext() and APInt::zext() assert that the bit field must not have the same size as the parent scalar. Replacing those calls with sextOrTrunc(), zextOrTrunc(), sextOrSelf() and zextOrSelf() fixes the assertion failures.

So far we bailed if a required invariant load was potentially overwritten in
the SCoP. From now on we will optimistically assume it is actually invariant
and, to this end, restrict the valid parameter space.

- Fixed cdp intrinsic to only accept compile time
constant values previously you could pass in a
variable to the builtin which would result in
illegal llvm assembly output

- Renamed intrinsics.ll to intrinsics-coprocessor.ll
as all the tests were testing coprocessor instructions,
also made the test checks match the full instruction.

Fixes for MUBUF_Atomic instructions to make operand list valid:
- For RTN insns, make a copy of $vdata_in operand as $vdata.
- Do not add operand for GLC, it is hardcoded and comes as a token.
Workaround to avoid adding multiple default optional operands.
Tests added.
