[llvm-objcopy] Implement --set-section-flags.
Summary:
--set-section-flags is used to change the section flags (e.g. SHF_ALLOC) for given sections. The flags allowed are the same from the existing --rename-section=.old=.new[,flags] feature.
Additionally, make sure that --set-section-flag cannot be used with --rename-section (either the source or destination), since --rename-section accepts flags. This avoids ambiguity for something like "--rename-section=.foo=.bar,alloc --set-section-flag=.bar,code".

During the lowering of a switch that would result in the generation of a

conditional branch is inserted to jump to the default block. In case the
default block is unreachable, this conditional jump can be omitted. This

[ThinLTO] Refine reachability check to fix compile time increase
Summary:
A recent fix to the ThinLTO whole program dead code elimination (D56117)
increased the thin link time on a large MSAN'ed binary by 2x.
It's likely that the time increased elsewhere, but was more noticeable
here since it was already large and ended up timing out.
That change made it so we would repeatedly scan all copies of linkonce
symbols for liveness every time they were encountered during the graph
traversal. This was needed since we only mark one copy of an aliasee as
live when we encounter a live alias. This patch fixes the issue in a
more efficient manner by simply proactively visiting the aliasee (thus
marking all copies live) when we encounter a live alias.
Two notes: One, this requires a hash table lookup (finding the aliasee
summary in the index based on aliasee GUID). However, the impact of this
seems to be small compared to the original pre-D56117 thin link time. It
could be addressed if we keep the aliasee ValueInfo in the alias summary
instead of the aliasee GUID, which I am exploring in a separate patch.
Second, we only populate the aliasee GUID field when reading summaries
from bitcode (whether we are reading individual summaries and merging on
the fly to form the compiled index, or reading in a serialized combined
index). Thankfully, that's currently the only way we can get to this
code as we don't yet support reading summaries from LLVM assembly
directly into a tool that performs the thin link (they must be converted
to bitcode first). I added a FIXME, however I have the fix under test
already. The easiest fix is to simply populate this field always, which
isn't hard, but more likely the change I am exploring to store the
ValueInfo instead as described above will subsume this. I don't want to
hold up the regression fix for this though.

then make more elightened decisions about ordering for DBG_VALUE placement.

[llvm-objdump] - Implement the --adjust-vma option.
GNU objdump's help says: "--adjust-vma: Add OFFSET to all displayed section addresses"
In real life what it does is a bit more complicated
(and IMO not always reasonable. For example, GNU objdump prints not only VMA, but also LMA
for sections. And with --adjust-vma it adjusts LMA, but only when a section has relocations.
llvm-objsump does not seem to support printing LMAs yet, but GNU's logic anyways does not
make sense for me here).
This patch tries to adjust VMA. I tried to implement a reasonable approach.
I am not adjusting sections that are not allocatable. As, for example, adjusting debug sections
VA's and rel[a] sections VA's should not make sense. This behavior seems to be GNU compatible.

[CMake] Use __libc_start_main rather than fopen when checking for C library
The check_library_exists CMake uses a custom symbol definition. This
is a problem when checking for C library symbols because Clang
recognizes many of them as builtins, and returns the
-Wbuiltin-requires-header (or -Wincompatible-library-redeclaration)
error. When building with -Werror which is the default, this causes
the check_library_exists check fail making the build think that C
library isn't available.
To avoid this issue, we should use a symbol that isn't recognized by
Clang and wouldn't cause the same issue. __libc_start_main seems like
reasonable choice that fits the bill.
