TargetLibraryInfoWrapperPass is a dependency of
SCCP but it's not listed as such. Chandler pointed
out this is an easy mistake to make which only
surfaces in weird crashes with some flag combinations.
This code will go away anyway at some point in the
future, but as long as it's (still) exercised, try
to make it correct.

This reverts commit r221331 and reinstate r220932 as discussed in D19271.
Original commit message was:
This patch adds an llvm_call_once which is a wrapper around
std::call_once on platforms where it is available and devoid
of bugs. The patch also migrates the ManagedStatic mutex to
be allocated using llvm_call_once.
These changes are philosophically equivalent to the changes
added in r219638, which were reverted due to a hang on Win32
which was the result of a bug in the Windows implementation
of std::call_once.

It seems that cl will emit the export directives for Windows ARM targets. The
fact that it did this had originally been missed and this functionality was
never implemented. This makes it possible to rely solely on the source code for
indicating what the exported interfaces are and brings us more compatibility
with cl.

Without a diagnostic handler installed, llc's behaviour is to exit on the first
error that it encounters. This is very different from the behaviour of clang
and other front ends, which try to gather as many errors as possible before
exiting.
This commit adds a diagnostic handler to llc, allowing it to find and report
more than one error. The old behaviour is preserved under a flag (-exit-on-error).
Some of the tests fail with the new diagnostic handler, so they have to use the
new flag in order to run under the previous behaviour. Some of these are known
bugs, others need further investigation. Ideally, we should fix the tests and
remove the flag at some point in the future.
Reapplied after fixing the LLDB build that was broken due to the new
DiagnosticSeverity in LLVMContext.h.
Patch by Diana Picus.

Summary:
The MIPS IAS can now pass 'ninja check-all', recurse, build a bootable linux
kernel, and pass a variety of LNT testing.
Unfortunately we can't enable it by default for 64-bit targets yet since the N32
ABI is still very buggy and this also means we can't enable it for N64 either
because we can't distinguish between N32 and N64 in the relevant code.

Suggested by Adrian. This is NFC right now but is more clean and
robust against future potential new debug info intrinsics.

compiler-rt/libgcc shift routines expect the shift count to be an i32, so
use i32 as the shift count for shifts that are legalized to libcalls. This
also reverts r268991, now that the signatures are correct.

Summary:
This code is intended to be used as part of LLD's PDB writing. Until
that exists, this is exposed via llvm-readobj for testing purposes.
Type stream merging uses the following algorithm:
- Begin with a new empty stream, and a new empty hash table that maps
from type record contents to new type index.
- For each new type stream, maintain a map from source type index to
destination type index.
- For each record, copy it and rewrite its type indices to be valid in
the destination type stream.
- If the new type record is not already present in the destination
stream hash table, append it to the destination type stream, assign it
the next type index, and update the two hash tables.
- If the type record already exists in the destination stream, discard
it and update the type index map to forward the source type index to
the existing destination type index.

- Where we were returning a node before, call ReplaceNode instead.
- Where we would return null to fall back to another selector, rename
the method to try* and return a bool for success.
- Where we were calling SelectNodeTo, just return afterwards.

I missed the fvmlib_command and the sub_framework_command, as well as a few uses of the dylib_command, dylinker_command, and linkedit_data_command.
This should now be a pretty complete listing. The only case I'm not sure about is LC_PREPAGE which doesn't seem to be referenced directly anywhere in LLVM.
