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.

This is a fix due to the addition of the new DiagnosticSeverity in
LLVMContext.h. This may warrant a change in name to be LLDB specific
but I leave that to the LLDB experts to refactor.

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.

This is essential for iterating across macros properly, which LLDB does when
loading macros from modules. A naiver version of this patch (without the
conditional) caused assertion failures in the testsuite, but this version should
be safe.
Thanks to Ben Langmuir for the refinement that made this work.

IdentifierInfos are assigned builtin IDs during parsing, but Idents.get() does
not do that work. So the ASTImporter needs to additionally set the builtin ID
for the newly-created IdentifierInfo. This patch does that.
Currently ASTMerge tests only check syntax and the ASTMatchers don't check for
builtin IDs, so this is tricky to test, but LLDB will have a test for this.

Every class as parsed by Clang has a forward declaration of itself as a member:
class A {
class A;
...
}
but when the parser generates this it ensures that the RecordTypes for the two
are the same. This makes (among other things) inheritance work. This patch
fixes a bug where the ASTImporter generated two separate RecordTypes when
importing the class and the contained forward declaration, and adds a test case.
Thanks to Doug Gregor for advice on this.

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:
print build errors nicely in test output
This test infrastructure change adds a new Python exception
for test subject builds that fail. The output of the build
command is captured and propagated to both the textual test
output display code and to the test event system.
The ResultsFormatter objects have been modified to do something
more useful with this information. The xUnit formatter
now replaces the non-informative Python build error stacktrace
with the build error content. The curses ResultsFormatter
prints a 'B' for build errors rather than 'E'.
The xUnit output, in particular, makes it much easier for
developers to track down test subject build errors that cause
test failures when reports come in from CI.

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.

Unlike sys::fs::recursive_directory_iterator,
vfs::recursive_directory_iterator does not implement the level() method,
which tells how deep in the directory tree the current iterator is. This
is needed in the vfs::recursive_directory_iterator so that future
improvements to the crash reproducer will be able to properly access
header for umbrellas when looking into the VFS.
