Ahmed Bougacha 2448ef5f33 [AArch64] Avoid vector->load dependency cycles when creating LD1*post.

Note that the opposite load->vector dependency is already obvious in:

David Majnemer dcd89368cb [WinEH] Reusing HandlerType entries leads to small CatchHigh values
CatchHigh may be smaller than TryHigh if we reuse an outlined catch
handler for two different invokes with different EH states.  We have no
evidence which shows that CatchHigh must be greater than TryHigh or
TryLow.  We can revisit this if we turn out to be wrong.

Rafael Espindola db8a58688d Compute A-B if both A and B are in the same comdat section.
Part of pr23272.

A small annoyance with the assembly syntax we implement is that given an
expression there is no way to know if what is desired is the value of that
expression for the symbols in this file or for the final values of those
symbols in a link.

The first case is useful for use in sections that get discarded or ignored
if the section they are describing is discarded.

For axample, consider A-B where A and B are in the same comdat section.

We can compute the value of the difference in the section that is present in
the current .o and if that section survives to the final DSO the value will
still will be correct.

But the section is in a comdat. Another section from another object file
might be used istead. We know that that section will define A and B, but
we have no idea what the value of A-B might be.

In practice we have to assume that the intention is to compute the value
in the current section since otherwise the is no way to create something like
the debug aranges section.

Aaron Ballman 63c7605a5b Suppressing the C4324 warnings generated by MSVC. This is the only declarative instance that would generate the warning, but it accounted for about 525+ warnings due to template instantiations. This is a marginal-value warning which we may decide to disable more broadly, but since this header is in Support and may be used out of tree, it's a low burden for us to be warning-free in this case.

When debugging LTO issues with ld64, we use -save-temps to save the merged

The saved bitcode file is already internalized, so we can call

Stop storing the `MDLocalVariable` in the `DebugLocEntry::Value`s.  We

variable/inlined-at pair, so the variable never actually changes here.

Kit Barton f4669f5905 Add support for v1i128 type.
The v1i128 type is needed for the quadword add/substract instructions introduced
in POWER8. Futhermore, the PowerPC ABI specifies that parameters of type v1i128
are to be passed in a single vector register, while parameters of type i128 are
passed in pairs of GPRs. Thus, it is necessary to be able to differentiate
between v1i128 and i128 in LLVM.

Kit Barton 7291802533 Add the i128 builtin type to LLVM.
The i128 type is needed as a builtin type in order to support the v1i128 vector
type. The PowerPC ABI requires that the i128 and v1i128 types are handled
differently when passed as parameters to functions (i128 is passed in pairs of
GPRs, v1i128 is passed in a single vector register).

Ilia K d854180afb MI support for '-var-create $regname' command.
Summary:
This command is currently processed using expression evaluation, meaning the variable binds to the result of the expression not the register.
Therefore any subsequent calls to '-var-assign' will not update the register. Fixed by detecting '$' prefix for registers according to specification.

There are others that should also be moved. This patch sticks to the ones that
are obviously non-functional. The others have minor mistakes that need fixing
at the same time, mostly involving checks for 64-bit GPR's instead of checks
for 64-bit pointers.
