There's an overloading of the "movsd" and "cmpsd" instructions, e.g. movsd can be either "Move Data from String to String" or "Move or Merge Scalar Double-Precision Floating-Point Value".
The former should produce warnings when parsing a memory operand that is not ESI/EDI, but the latter should not.
Fixed the code to produce warnings only after making sure we're dealing with the first case.
Expanded the tests of the produced warnings + fixed RUN line of the test so that it would check both stdout and stderr

Summary:
The previous form, taking opcode and type, is moved to an internal
helper and the new form, taking an instruction, is a wrapper around this
helper.
Although this is a slight cleanup on its own, the main motivation is to
refactor the constant folding API to ease migration to opaque pointers.
This will be follow-up work.

Currently the SI scheduler can be selected via command line option,
but it turned out it would be better if it was selectable via a Target Attribute.
This patch adds "si-scheduler" attribute to the backend.

Summary:
Mark the LLVMGlobalISel library as optional in
LLVMBuild.txt, since the library is only built
if LLVM_BUILD_GLOBAL_ISEL is set. Without doing
this, llvm-config includes the library in the
list of components regardless of whether it's
built, and then will error out when asked for
the library names/paths.

The binary contains two (merged) covmap sections which
have duplicate CovMapRecords from comdat (template instantation).
This test makes sure the reader reads it properly. It also
tests that the coverage data from different instantiations
of the same template function are properly merged in show

This patch adds the necessary plumbing to cmake to build the sources related to
GlobalISel.
To build the sources related to GlobalISel, we need to add -DBUILD_GLOBAL_ISEL=ON.
By default, this is OFF, thus GlobalISel sources will not impact people that do
not explicitly opt-in.

Summary:
This adds a new kind of operand bundle to LLVM denoted by the
`"gc-transition"` tag. Inputs to `"gc-transition"` operand bundle are
lowered into the "transition args" section of `gc.statepoint` by
`RewriteStatepointsForGC`.
This removes the last bit of functionality that was unsupported in the
deopt bundle based code path in `RewriteStatepointsForGC`.

Some architecture specific ELF section flags might have the same value
(for example SHF_X86_64_LARGE and SHF_HEX_GPREL) and we have to check
machine architectures to select an appropriate set of possible flags.
The patch selects architecture specific flags into separate arrays
`ElfxxxSectionFlags` and combines `ElfSectionFlags` and `ElfxxxSectionFlags`
before pass to the `StreamWriter::printFlags()` method.

The selection process being split into separate passes, we need generic opcodes

When a symbol S shows up in an expression in assembly there are two
possible interpretations
* The expression is referring to the value of S in this file.
* The expression is referring to the value after symbol resolution.
In the first case the assembler can reason about the value and try to
produce a relocation.
In the second case, that is only possible if the symbol cannot be
preempted.
Assemblers are not very consistent about which interpretation gets used.
This changes MC to agree with GAS in the case of an expression of the
form "Sym - WeakSym".

The test case will crash without this patch because the subsequent call to
hasUnsafeAlgebra() assumes that the call instruction is an FPMathOperator
(ie, returns an FP type).
This part of the function signature check was omitted for the sqrt() case,
but seems to be in place for all other transforms.
Before:
http://reviews.llvm.org/rL257400
...we would have needlessly continued execution in optimizeSqrt(), but the
bug was harmless because we'd eventually fail some other check and return
without damage.
This should fix:

There was support for writing the AArch64 big endian data fixup entries in
the .eh_frame section in BE. This is changed to write all such fixup
entries in BE with no restriction on the section. This is similar to
the existing support for fixup entries for ARM.
A test is added to check the length field in the .debug_line section as
this is an example of where such a fixup occurs.
