- pass through to base-class implementation when raised exception is not from an LLDBTest
- should make the test suite errors a little easier to root-cause

Call into ComputeMaskedBits to figure out which bits are set on both add
operands and determine if the value is a power-of-two-or-zero or not.

It will now only convert the arguments / return value and call
the underlying function if the types are able to be bitcasted.
This avoids using fp<->int conversions that would occur before.

When registers must be live throughout the scheduling region, increase
the limit for the register class. Once we exceed the original limit,
they will be spilled, and there's no point further reducing pressure.
This isn't a perfect heuristics but avoids a situation where the
scheduler could become trapped by trying to achieve the impossible.

Committing r187204 with fixes for darwin. Note that one of the lit tests are
disabled on windows due to a bug in writing header replacements to file.
Header replacements are now written to disk in YAML format for an external tool
to merge. A unique file will be created in the same directory as the header
with all replacements that came from a source file that included the header
file. The YAML file will have:
- Name of the file
- Transform ID that generated the replacement
- Offset
- Length
- Replacement text
Any tool reading these replacements should read them using the
TransformDocument struct.

on the system, and report it when running the driver in verbose mode.
Without this it is essentially impossible to understand why a particular
GCC toolchain is used by Clang for libstdc++, libgcc, etc.
This also required threading a hook through the toolchain layers for
a specific toolchain implementation to print custom information under
'clang -v'. The naming here isn't spectacular. Suggestions welcome.

to handle the case of an integer constant (DWARF 3 and later).
- Fixes tests that assert in RecordLayoutBuilder::updateExternalFieldOffset
because LLDB was providing an external AST source with missing member offsets.

Instantiate RegisterContext... based on getOS() instead of with
compile-time #ifdef-ery.
The assert() here is unfortunate, but better than crashing with no
explanation.
This change is equivalent to r186865 for elf-core.

When simplifying a (or (and B A) (and C ~A)) to a (VBSL A B C) ensure that the
bitwidth of the second operands to both ands match before comparing the negation
of the values.
Split the check of the value of the second operands to the ands. Move the cast
and variable declaration slightly higher to make it slightly easier to follow.
