Instead just rely on LLDB_LOG().
This is part of an effort to sort out dependency hell in LLDB.
Error is in Utility, but Log is in Core. Core can depend on
Utility, but not vice versa. So this patch moves the knowledge
about how to log Errors from the Error class to the Log file.

Endian functions only support reading and writing when the
endianness is known at compile time. This patch adds overloads
where the endianness is a runtime value, and then delegates the
compile-time versions to the runtime versions.

Summary: When type casting of the return value is needed, promoteIndirectCall will return the type casting instruction instead of the direct call. This patch changed to return the direct call instruction instead.

When splitting up one store into several in splitStoreSplat we have to
make sure we get the MachinePointerInfo right, otherwise alias
analysis thinks they all store to the same location. This can then
cause invalid scheduling later on.

Summary:
The std::call_once implementation in libstdc++ has problems on few systems: NetBSD, OpenBSD and Linux PPC. LLVM ships with a homegrown implementation llvm::call_once to help on these platforms.
This change is required in the NetBSD LLDB port. std::call_once with libstdc++ results with crashing the debugger.

Apparently "test standalone compiler-rt" still requires -ldl and -lrt for
Scudo even with --gc-sections. I am not entirely sure why, so if anybody has
some input, feel free to chime in.
In the meantime, add again those two to fix the test.

GCC 7 will predefine two new macros on s390x:
- __ARCH__ indicates the ISA architecture level
- __VX__ indicates that the vector facility is available
This adds those macros to clang as well to ensure continued
compatibility with GCC.

Currently we only combine shuffle nodes if they have a single user to prevent us from causing code bloat by splitting the shuffles into several different combines.
We don't take into account that in some cases we will already have combined all the users during recursively calling up the shuffle tree.
This patch keeps a list of all the shuffle nodes that have been combined so far and permits combining of further shuffle nodes if all its users are in that list.

Previously only the superscalar scheduled expansion of the dla macro for
MIPS64 was implemented. If assembler temporary register is not available
and the optional source register is not the destination register, synthesize
the address using the naive solution of adds and shifts.
This partially resolves PR/30383.

%mul1 = mul nsw i32 %add, %conv
%add2 = add nsw i32 %mul1, %add
%mul3 = mul nsw i32 %add2, %add
; repeat couple of thousands times
that can be produced by loop unroll, getAddExpr() tries to recursively construct SCEV and runs almost infinite time.
Added recursion depth restriction (with new parameter to set it)

Previously the method would simply return false, causing every single

This adds inline assembly constraint support for the AVR target.
This patch is derived from the code in
