Store-immediate instructions have a non-extendable offset. Since the
actual offset for a stack object is not known until much later, only
generate these stores when the stack size (at the time of instruction
selection) is small.

Summary:
This patch is part of 3 patches that together form a single patch, but must be introduced in stages in order not to break things.
The way that LLVM interprets DW_OP_plus in DIExpression nodes is basically that of the DW_OP_plus_uconst operator since LLVM expects an unsigned constant operand. This unnecessarily restricts the DW_OP_plus operator, preventing it from being used to describe the evaluation of runtime values on the expression stack. These patches try to align the semantics of DW_OP_plus and DW_OP_minus with that of the DWARF definition, which pops two elements off the expression stack, performs the operation and pushes the result back on the stack.
This is done in three stages:
• The first patch (LLVM) adds support for DW_OP_plus_uconst.
• The second patch (Clang) contains changes all its uses from DW_OP_plus to DW_OP_plus_uconst.
• The third patch (LLVM) changes the semantics of DW_OP_plus and DW_OP_minus to be in line with its DWARF meaning. This patch includes the bitcode upgrade from legacy DIExpressions.

When a mux instruction is created from a pair of complementary conditional
transfers, it can be placed at the location of either the earlier or the
later of the transfers. Since it will use the operands of the original
transfers, putting it in the earlier location may hoist a kill of a source
register that was originally further down. Make sure the kill flag is
removed if the register is still used afterwards.

While simplifying branches in the MachineInstr representation, the
routine BuildCondBr must preserve flags on register MachineOperands. In
particular, it must preserve the <undef> flag.
This fixes a bug that is unlikely to occur in any real scenario, but
which bugpoint is likely to introduce.

Much of PR32037's compile time regression is due to getTargetConstantBitsFromNode always creating large (>64bit) APInts during the bitcasting from the source data to the destination bitwidth.
This commit avoids this bitcast stage if the data is already the correct bitwidth.

These symbols were previously not being marked as functions
so were appearing as globals instead, and with the incorrect
relocation type.
Without this fix, objects that take address of external
functions include them as global imports rather than function
imports which then fails at link time.

I accidentally combined this patch with one for adding more tests, they
should be separated.

This just forwarded to the same signature in User. The version in User is protected so there's no danger of anyone outside of PHINode constructing with the wrong operator new. All PHINodes are created by a static Create function in PHINode.
I believe at one point in history this called User::operator new(s, 0) so it was useful then.

Previously we were writing the value function index space
value but for these types of relocations we want to be

User has 3 signatures for operator new today. They take a single size, a size and a number of users, and a size, number of users, and descriptor size.
Historically there used to only be one signature that took size and a number of uses. Long ago derived classes implemented their own versions that took just a size and would call the size and use count version. Then they left an unimplemented signature for the size and use count signature from User. As we moved to C++11 this unimplemented signature because = delete.
Since then operator new has picked up two new signatures for operator new. But when the 3 argument version was added it was never added to the delete list in all of the derived classes where the 2 argument version is deleted. This makes things inconsistent.
I believe once one version of operator new is created in a derived class name hiding will take care of making all of the base class signatures unavailable. So I don't think the deleted lines are needed at all.
This patch removes all of the deletes in cases where there is an override or there is already a delete of another signature (that should trigger name hiding too).

When we get an unknown symbol type, we might as well at least
dump it. Same goes for round-tripping through YAML, we can
dump the record contents as raw bytes even if we don't know
how to interpret it semantically.

It doesn't seem relevant to set an address space limit - this isn't
important in any sense that I'm aware & it gets in the way of things
that use a lot of address space, like llvm-symbolizer.
This came up when I realized that bugpoint regression tests were much
slower with -gsplit-dwarf than plain -g. Turned out that bugpoint
subprocesses (opt, etc) were crashing and doing symbolization - but
bugpoint runs those subprocesses with a 400MB memory limit. So with
plain -g, mmaping the opt binary would exceed the memory limit, fail,
and thus be really fast - no symbolization occurred. Whereas with
-gsplit-dwarf, comically, having less to map in, it would succeed and
then spend lots of time symbolizing.
I've fixed at least the critical part of bugpoint's perf problem there
by adding an option to allow bugpoint to disable symbolization. Thus
improving the perfromance for -gsplit-dwarf and making the -g-esque
speed available without this quirk/accidental benefit.

This one occurred when we were dumping symbols, we have code
that is prepared to dump many different types of symbols,
including symbols which reference an ID stream. So when creating
the dumper object, we assume that there is an ID stream. Fix
this assumption.

The last fix required the user to manually add the required
feature. This caused an LLD test to fail because I failed to
update LLD. In practice we can hide this logic so it can just
be transparently added when we write the PDB.
llvm-svn: 305236
Older PDBs don't have this. Its presence is detected by using
the various "feature" flags that come at the end of the PDB
Stream. Detect this, and don't try to dump the ID stream if the
features tells us it's not present.
