ELFFile would be a class that rest of the targets would derive from.
To keep the implementation clean, separate the implementation from
rest of the Header file.

e.g. thumbv7m-apple-ios3.0.0-eabi, then it should mean it's an iOS target. For
embedded targets, the OS should be unknown, e.g. thumbv7m-apple-unknown-macho.
Since Tim has recently fixed the triple, r195149 is no longer needed.

Placed the MC variant diagnostics in the wrong directory accidentally. Move
them into their respective architecture specific directories.

If a complex expression was passed to the .word directive and the first part of
the directive failed to parse, a secondary diagnostic would be produced that
would clutter the error diagnostics. Improve the diagnostics by consuming the
remainder of the statement.

An emitted diagnostic for an invalid relocation variant would place the caret on
the token following the relocation variant indicator or at the end of the line
if there was no following token. This change corrects the placement of the
caret to point to the token.

Count the number of computational steps that have been used to solve the
dependence problem and abort in case we reach the "compute-out". This ensures we
do not hang forever in cases the dependence problem is too difficult to solve.
There is just a single case in the LLVM test-suite that runs into the
compute-out. Even in this case, we can probably coalesce some of the parameters
(i32 b, i32 b zext i64, ...) to simplify the problem enough to not hit the
compute out. However, for now we set the compute out in place to address the
general issue. The compute out was choosen such that it stops on a recent laptop
after about 8 seconds.

allow the user to impose a bound on the number of low-level operations
This should allow the user to deterministically limit the effort spent on a
computation.

It was calling the utility wrapper that now requires a constant string
following clang r200132. The StringRef version on DiagnosticIDs appears to have
been what was intended so change to that.
llvm-svn: 200142
This now requires a compile-time constant string so let's build proper
diagnostic IDs and pass through the inputs as arguments.
Tracks clang changes in r200132.

These were:
* noreorder handling on the target object streamer and asm parser.
* setting the initial flag bits based on the enabled features.
* setting the elf header flag for micromips
It is *really* depressing I am the one doing this instead of someone at
mips actually taking the time to understand the infrastructure.
llvm-svn: 200138
Replace the last incorrect uses and templatize the function to require a
compile-time constant string preventing further misuse.
The diagnostic formatter expects well-formed input and has undefined behaviour
with arbitrary input or crafted user strings in source files. Accepting user
input would also have caused unbounded generation of new diagnostic IDs which
can be problematic in long-running sessions or language bindings.
This completes the work to fix several incorrect callers that passed user
input or raw messages to the diagnostics engine where a constant format string
was expected.
llvm-svn: 200132
This has a few advantages:
* Only targets that use a MCTargetStreamer have to worry about it.
* There is never a MCTargetStreamer without a MCStreamer, so we can use a
reference.
* A MCTargetStreamer can talk to the MCStreamer in its constructor.
