Recommit r308327 2nd time: Add a warning for missing

The first recommit (r308441) caused a "non-default #pragma pack value might
change the alignment of struct or union members in the included file" warning
in LLVM itself. This recommit tweaks the added warning to avoid warnings for
#includes that don't have any records that are affected by the non-default
alignment. This tweak avoids the previously emitted warning in LLVM.
Original message:
This commit adds a new -Wpragma-pack warning. It warns in the following cases:
- When a translation unit is missing terminating #pragma pack (pop) directives.
- When entering an included file if the current alignment value as determined
by '#pragma pack' directives is different from the default alignment value.
- When leaving an included file that changed the state of the current alignment
value.

[COFF, ARM64] Fix symbol offsets in ADRP/ADD/LDR/STR relocations
In COFF, a symbol offset can't be stored in the relocation (as is
done in ELF or MachO), but is stored as the immediate in the
instruction itself. The immediate in the ADRP thus is the symbol
offset in bytes, not in pages. For the PAGEOFFSET_12A/L relocations,
ignore any offset outside of the lowest 12 bits; they won't have any
effect on the ADD/LDR/STR instruction itself but only on the associated
ADRP.
This is similar to how the same issue is handled for MOVW/MOVT
instructions in ELF (see e.g. SVN r307713, and r307728 in lld).
This fixes "fixup out of range" errors while building larger object
files, where temporary symbols end up as a plain section symbol and
an offset, and fixes any cases where the symbol offset mean that
the actual target ended up on a different page than the symbol
itself.

This is NFC in terms of externally visible behaviour but some internals have
changed slightly. State.MIs is no longer reset between each rule that is
attempted because it's not necessary to do so. As a consequence of this the

relaxed to only affect recorded instructions that require new elements to be

them. We also need to disable the select simplification when one of select

[lit] Fix UnboundLocalError for invalid shtest redirects

UnboundLocalError: local variable 'r' referenced before assignment

[scudo] Check for pvalloc overflow
Summary:
Previously we were rounding up the size passed to `pvalloc` to the next
multiple of page size no matter what. There is an overflow possibility that
wasn't accounted for. So now, return null in the event of an overflow. The man
page doesn't seem to indicate the errno to set in this particular situation,
but the glibc unit tests go for ENOMEM (https://code.woboq.org/userspace/glibc/malloc/tst-pvalloc.c.html#54)
so we'll do the same.
Update the aligned allocation funtions tests to check for properly aligned
returned pointers, and the `pvalloc` corner cases.

[LTO] Prevent dead stripping and internalization of symbols with sections
Summary:
ELF linkers generate __start_<secname> and __stop_<secname> symbols
when there is a value in a section <secname> where the name is a valid
C identifier. If dead stripping determines that the values declared
in section <secname> are dead, and we then internalize (and delete)
such a symbol, programs that reference the corresponding start and end
section symbols will get undefined reference linking errors.
To fix this, add the section name to the IRSymtab entry when a symbol is
defined in a specific section. Then use this in the gold-plugin to mark
the symbol as external and visible from outside the summary when the
section name is a valid C identifier.

UB member calls (this=nullptr), i.e it's causing user programs to crash

[StaticAnalyzer] Completely unrolling specific loops with known bound option
This feature allows the analyzer to consider loops to completely unroll.
New requirements/rules (for unrolling) can be added easily via ASTMatchers.
Right now it is hidden behind a flag, the aim is to find the correct heuristic
and create a solution which results higher coverage % and more precise
analysis, thus can be enabled by default.
Right now the blocks which belong to an unrolled loop are marked by the
LoopVisitor which adds them to the ProgramState.
Then whenever we encounter a CFGBlock in the processCFGBlockEntrance which is
marked then we skip its investigating. That means, it won't be considered to
be visited more than the maximal bound for visiting since it won't be checked.
