If a return value is explicitly rounded to 64 bits, an additional zext
instruction is emitted, and in some cases it prevents tail call
optimization.

As discussed in D100225, this rounding is not necessary and can be
disabled.

This reverts commit 3655f075.

It caused assertion failures related to setLastUser in polly builds.

Root node in ProfiledCallGraph.

In ProfiledCallGraph::addProfiledFunction, to add a function symbol into the
ProfiledCallGraph, currently an uninitialized ProfiledCallGraphNode node is
created by ProfiledFunctions[Name] and inserted into Callees set of Root node
before the node is initialized. The Callees set use
ProfiledCallGraphNodeComparer as its comparator so the uninitialized
ProfiledCallGraphNode may fail to be inserted into Callees set if it happens
to contain a name in memory which has been inserted into the Callees set
before. The problem will prevent some function symbols from being annotated
with profiles and cause performance regression. The patch fixes the problem.

When dumping multiple pieces of information (e.g. --all-headers),
there is sometimes no separator between two pieces.
This patch uses the "\nheader:\n" style, which generally improves
compatibility with GNU objdump.

Note: objdump -t/-T does not add a newline before "SYMBOL TABLE:" and "DYNAMIC SYMBOL TABLE:".
We add a newline to be consistent with other information.

`objdump -d` prints two empty lines before the first 'Disassembly of section'.
We print just one with this patch.

It also holds search flags that can be fetched by resolvers to look inlined

This patch moves the Declaration class from the Symbol library to the
Core library. This will allow to use it in a more generic fashion and
aims to lower the dependency cycles when it comes to the linking.

The patch also does some cleaning up by making column information
permanent and removing the LLDB_ENABLE_DECLARATION_COLUMNS directives.

This fixes PR49821, and avoids "ld.lld: error: test.o:(.rodata.str1.1):
offset is outside the section" errors when linking MIPS objects with
negative R_MIPS_LO16 implicit addends.

ld.lld handles R_MIPS_HI16/R_MIPS_LO16 separately, not as a whole, so it
doesn't know that an R_MIPS_HI16 with implicit addend 1 and an
R_MIPS_LO16 with implicit addend -32768 represents 32768, which is in
range of a MergeInputSection. We could introduce a new RelExpr member
(like R_RISCV_PC_INDIRECT for R_RISCV_PCREL_HI20 / R_RISCV_PCREL_LO12)
but the complexity is unnecessary given that GNU as keeps the original
symbol for this case as well.

Adds a new test case for PR49821, and also updates two other test cases
that are affected by this change.

The problem only happens with constexpr variable, for constexpr variable,
variable is not marked during parser variable.   This is because compiler
might find some var's associate expressions may not actully an odr-used
later,  the variables get kept in MaybeODRUseExprs, in normal case, at
end of process fullExpr, the variable will be marked during the call to
CleanupVarDeclMarking(). Since we are processing expression of OpenMP
clauses, and the ActOnFinishFullExpr is not getting called that casue
variable is not get marked.

One way to fix this is to call CleanupVarDeclMarking() in EndOpenMPClause

Currently, the position hint of an entry in the persistent auto
dictionary is fixed to 1. As a consequence, with a 50% chance, the entry
is applied right after the first byte of the input. As the position 1
does not appear to have any particular significance, this is likely a
bug that may have been caused by confusing the constructor parameter
with a success count.

This commit resolves the issue by preserving any existing position hint
or disabling the hint if the original entry didn't have one.
