to the way we currently expect target selection to work -- clients are supposed
to have control over what targets are available.

Conservatively returns zero when the GV does not specify an alignment nor is it
initialized. Previously it returns ABI alignment for type of the GV. However, if
the type is a "packed" type, then the under-specified alignments is attached to
the load / store instructions. In that case, the alignment of the type cannot be
trusted.

Their alignments are intentionally under-specified.

if !UseImm, in which case they have been initialized.

Some files installed by clang are not relevant for general users and we'd like
to be able to install them to a different location. This adds a new
--with-internal-prefix configure option and a corresponding PROJ_internal_prefix
makefile variable, which defaults to the standard prefix. A tool makefile
can specify that it should be installed to this internal prefix by defining
INTERNAL_TOOL.

When wait() has finished, opened handles (especially writing stdout to file) might not be released immediately.
To wait for released, poll to attempt renaming.

Now that it needs to be exported in a public header (Valgrind.h)
it should be prefixed to avoid collision with other projects.
Add it to llvm-config.h as well.
This'll require regenerating the configure script after this
commit, but I don't have the required autoconf version.

Also re-alphabetize it from its position when it was LLVM_HOST_TRIPLE.

gcc, though I thought it was older (my gcc 4.4 has it as a local patch. Whoops!)
This fixes PR10589.
Also add some debugging statements.
Remove GcnoFiles, the mapping from CompilationUnit to raw_ostream. Now that we
start by iterating over each CU and descending into them, there's no need to
maintain a mapping.

fallthrough) in cases where we might fail to rotate an exit to an outer
loop onto the end of the loop chain.
Having *some* rotation, but not performing this rotation, is the primary
fix of thep performance regression with -enable-block-placement for
Olden/em3d (a whopping 30% regression). Still working on reducing the
test case that actually exercises this and the new rotation strategy out
of this code, but I want to check if this regresses other test cases
first as that may indicate it isn't the correct fix.
