There is a bug reported at https://bugs.llvm.org/show_bug.cgi?id=48938
After looking through the glibc, I found the `atexit(f)` is the same as `__cxa_atexit(f, NULL, NULL)`. In orc runtime, we identify different JITDylib by their dso_handle value, so that a NULL dso_handle is invalid. So in this patch, I added a `PlatformJDDSOHandle` to ELFNixRuntimeState, and functions which are registered by atexit will be registered at PlatformJD.

CodeGenFunction::InitTempAlloca() inits the static alloca within the

For example, the current instruction insertion point (pointed by the
instruction builder) could be a program point which is hit multiple

alloca is initialized every time the program point is hit.
Hence remove CodeGenFunction::InitTempAlloca(), and initialize the

[InlineCost] model calls to llvm.is.constant* more carefully
llvm.is.constant* intrinsics are evaluated to 0 or 1 integral values.
A common use case for llvm.is.constant comes from the higher level
__builtin_constant_p. A common usage pattern of __builtin_constant_p in
the Linux kernel is:
void foo (int bar) {
if (__builtin_constant_p(bar)) {
// lots of code that will fold away to a constant.
} else {
// a little bit of code, usually a libcall.
}
}
A minor issue in InlineCost calculations is when `bar` is _not_ Constant
and still will not be after inlining, we don't discount the true branch
and the inline cost of `foo` ends up being the cost of both branches
together, rather than just the false branch.
This leads to code like the above where inlining will not help prove bar
Constant, but it still would be beneficial to inline foo, because the
"true" branch is irrelevant from a cost perspective.
For example, IPSCCP can sink a passed constant argument to foo:
const int x = 42;
void bar (void) { foo(x); }
This improves our inlining decisions, and fixes a few head scratching
cases were the disassembly shows a relatively small `foo` not inlined
into a lone caller.
We could further improve this modeling by tracking whether the argument
to llvm.is.constant* is a parameter of the function, and if inlining
would allow that parameter to become Constant. This idea is noted in a
FIXME comment.

[clang] Fix absolute file paths with -fdebug-prefix-map
Previously if you passed an absolute path to clang, where only part of
the path to the file was remapped, it would result in the file's DIFile
being stored with a duplicate path, for example:
```
!DIFile(filename: "./ios/Sources/bar.c", directory: "./ios/Sources")
```
This change handles absolute paths, specifically in the case they are
remapped to something relative, and uses the dirname for the directory,
and basename for the filename.
This also adds a test verifying this behavior for more standard uses as
well.

[clang-format-diff] Fix missing formatting for zero length git diff lines
If we only delete lines that are outer block statements (if, while, etc),

An example to repro:
1. Delete the if statment at line 118 in llvm/lib/CodeGen/Analysis.cpp.
2. Run `git diff -U0 --no-color HEAD^ | clang/tools/clang-format/clang-format-diff.py -i -p1`

This patch allows a visual studio solution file to be passed directly

requirements, without needing all the details of this configuration to
be built directly into Dexter or adding a config file that simply
duplicates existing settings in the VS solution.

Libc++ allows usage of
