Summary:
mesa3d will use the same kernel calling convention as amdhsa, but it will
handle everything else like the default 'unknown' OS type.

This matches gold and bfd, and is pretty much required by some linker
scripts. They end with commands like
foo 0 : { *(bar) }
if we put any SHF_ALLOC sections after they can have an address that
is too low.

computeKnownBits() already works for integer vectors, so allow vector types when calling that from InstCombine.
I don't think the change to use m_APInt in computeKnownBits is strictly necessary because we do check for
ConstantVector later, but it's more efficient to handle the splat case without needing to loop on vector elements.
This should work with InstSimplify, but doesn't yet, so I made that a FIXME comment on the test for PR24942:

This matches bfd behavior. It also makes future changes simpler as we
don't have to worry about ignoring these commands in multiple places

gcc and clang in gcc compatibility mode do not accept __forceinline. Use
the gcc attribute for them instead.

Summary:
When LLVM_LINK_LLVM_DYLIB is set, the libLLVM shared
library needs to be installed in the toolchain. Without
this chanage LLVM_INSTALL_TOOLCHAIN_ONLY combined with
LLVM_LINK_LLVM_DYLIB results in a broken install.

Recommitting after fixing AsmParser initialization and X86 inline asm
error cleanup.
Allow errors to be deferred and emitted as part of clean up to simplify
and shorten Assembly parser code. This will allow error messages to be
emitted in helper functions and be modified by the caller which has
better context.
As part of this many minor cleanups to the Parser:
* Unify parser cleanup on error
* Add Workaround for incorrect return values in ParseDirective instances
* Tighten checks on error-signifying return values for parser functions
and fix in-tree TargetParsers to be more consistent with the changes.
* Fix AArch64 test cases checking for spurious error messages that are
now fixed.
These changes should be backwards compatible with current Target Parsers
so long as the error status are correctly returned in appropriate
functions.

With fix for 2 bots. Details about the fix performed is on a review page.
Initial commit message:
This is PR30387:
From PR description:
We fail to parse
SECTIONS
{
foo :
{
*(sec0 EXCLUDE_FILE (zed1.o) sec1 EXCLUDE_FILE (zed2.o) sec2 )
}
}
The semantics according to bfd are:
Include sec1 from every file but zed1.o
Include sec2 from every file but zed2.o
Include sec0 from every file
Patch implements the support.

Summary:
This value is already defaulted to true in asan_internal.h.
Allow the value to be overriden in cases where exceptions are unavailable.

A follow-up patch will rename this pass and the source file accordingly,
but I figured the non-NFC change will be easier to spot in isolation.

This fixes pr30367, but more importantly, it changes how we compute offsets.
Now offset computation in a walk over linker script commands, like the
rest of assignAddresses. IMHO this is simpler to understand and if we
ever have to create multiple outputsections or chunks to change how we
handle test/ELF/linkerscript/alternate-sections.s it should be easier
to do it.

We used to only support instructions with same-type operands.
Instead, use the per-register type information to map each
operand more accurately.

reference. NFC.

When a phi node is finally lowered to a machine instruction it is
important that the lowered "load" instruction is placed before the
associated DEBUG_VALUE entry describing the value loaded.
Renamed the existing SkipPHIsAndLabels to SkipPHIsLabelsAndDebug to
more fully describe that it also skips debug entries. Then used the
"new" function SkipPHIsAndLabels when the debug information should not
be skipped when placing the lowered "load" instructions so that it is
placed before the debug entries.
