[cleanup] Stop specifying size overrides for BumpPtrAllocators.

These don't seem to have any real point. Let's start with
IndexingContext. I can't come up with any conceivable reason to have
many hundereds of thousands of these alive in an address space which
would make the 4x difference in allocated (but unused) memory for the
string scratch buffer a significant memory usage problem.

The EditedSource one is somewhat more surprising. This is an 8x increase
in the memory allocated (but not used) per editted source file. However,
for this to realistically be a problem, you would need to have over half
a million editted source files in a single address space, and even that
would only really have problems on 32-bit Windows where you really only
have 2gb of virtual address space. And what's more important, the fix to
this if it is actually an issue shouldn't be to shrink the allocator's
size, it is to pass a single allocator into *many* edited source file
objects and let them share the memory.

These were the only two uses of custom sized BumpPtrAllocators
(excluding ones in the JIT using a custom allocation strategy) in all of
LLVM, Clang, LLD, LLDB, or Polly. I don't think we actually need this
complexity in the primary BumpPtrAllocator at all and am planning to
remove it.

[analyzer] Handle the M_ZERO and __GFP_ZERO flags in kernel mallocs.

Add M_ZERO awareness to malloc() static analysis in Clang for FreeBSD,
NetBSD, and OpenBSD in a similar fashion to O_CREAT for open(2).
These systems have a three-argument malloc() in the kernel where the
third argument contains flags; the M_ZERO flag will zero-initialize the
allocated buffer.

This should reduce the number of false positives when running static
analysis on BSD kernels.

Additionally, add kmalloc() (Linux kernel malloc()) and treat __GFP_ZERO
like M_ZERO on Linux.

Future work involves a better method of checking for named flags without
hardcoding values.

[PGO] Add simplified branch weights for Objective-C for-collection loops.

Conceptually one of these loops is just a while-loop, but the actual code-gen
is more complicated. We don't instrument all the different control flow edges
to get accurate counts for each conditional branch, nor do I think it makes
sense to do so. Instead, make the simplifying assumption that the loop behaves
like a while-loop. Use the same branch weights for the first check for an
empty collection as would be used for the back-edge of a while loop, and use
that same weighting for the innermost loop, ignoring the possibility that there
may be some extra code to go fetch more elements.
