Error out if the user tries to use float-abi="hard" since it isn't
supported on darwin platforms. Previously clang issued no warnings or
erros and just passed the option to the backend, which had no effect on
code generation for targets using apcs.

This patch fixes PR24546, which demonstrates a segfault during the VSX
swap removal pass. The problem is that debug value instructions were
not excluded from the list of instructions to be analyzed for webs of
related computation. I've added the test case from the PR as a crash
test in test/CodeGen/PowerPC.

Arranging the language specific property section into readable groupings and adding a couple of notes about pass order, extensions, and the like.
For the record, suggestion for word smithing are welcomed. I'm happy to revise; I'm just trying to get *something* in place.

This change just groups the suggestions by broad topic. I'm planning a couple of follow on changes to improve the readability of this document.

Before:
DEPRECATED("Use NewClass::NewFunction instead.") int OldFunction(
const string ¶meter) {}
Could not be formatted at all, as clang-format would both require and
disallow the break before "int".

This patch adds support for dfsan on aarch64-linux with 42-bit VMA
(current default config for 64K pagesize kernels). The support is
enabled by defining the SANITIZER_AARCH64_VMA to 42 at build time
for both clang/llvm and compiler-rt. The default VMA is 39 bits.

Summary:
There were a number of issues about the way I have designed this test originally:
- it relied on single-stepping through large parts of code, which was slow and unreliable
- the threading libraries interfered with the exact thing we wanted to test
For this reason, I have rewritted the test using low-level linux api, which allows the test to be
much more focused. The functionality for other platforms will need to be tested separately.

The POSIX linker generally reports the load bias for the loaded
libraries but in some case it is useful to handle a library based on
absolute load address. Example usecases:
* Windows linker uses absolute addresses
* Library list came from different source (e.g. /proc/<pid>/maps)
