We need a way to show all the processes on android regardless of the user id.
When you run `platform process list`, you only see the processes with the same user as the user that launched lldb-server. However, it's quite useful to see all the processes, though, and it will lay a foundation for full apk debugging support from lldb.

We already did this for VTRUNCUS with a specific combination of
types. This extends this to VTRUNCS and handles any types where
a truncating store is legal.

The ExecuteCommand function in fuchsia used to prefix the
getOutputFile for each command run with the artifact_prefix flag if
it was available, because fuchsia components don't have a writable working
directory. However, if a file with a global path is provided, fuchsia
should honor that.
An example of this is using the global /tmp directory to store stuff.
In fuchsia it ended up being translated to data///tmp, whereas we want
to make sure it is using /tmp (which is available to components using the
isolated-temp feature).
To test this I made the change, compiled fuchsia with this toolchain and
ran a fuzzer with the -fork=1 flag (that mode makes use of the /tmp
directory). I also tested that normal fuzzing workflow was not affected
by this.

libunwind was using its own set of macros/functions for flag checking
which was similar but different from libc++ and libc++abi. This made
it difficult to replicate the same checks across projects, in fact
there were some checks that appear to have been copy & pasted from
another project and that were broken in the standalone libunwind build.
This change refactors flag checks to match libc++ and libc++abi using
a copy of HandleLibunwindFlags.cmake which is derived from the versions
used by the other projects. This also paves a road to deduplicating and
unifying HandleLibunwindFlags.cmake, HandleLibcxxabiFlags.cmake and
HandleLibcxxFlags.cmake post monorepo switch.

Now assembler generates two consecutive `.4byte` directives to store
64-bit `li.d' operand. The first directive stores high 4-byte of the
value. The second directive stores low 4-byte of the value. But on
64-bit system we load this value at once and get wrong result if the
system is little-endian.
This patch fixes the bug. It stores the `li.d' operand as a single
8-byte value.

If `li.s` or `li.d` loads zero into a FPR, it's not necessary to load

Teach buildMerge how to deal with scalar to vector kind of requests.
Prior to this patch, buildMerge would issue either a G_MERGE_VALUES
when all the vregs are scalars or a G_CONCAT_VECTORS when the destination
vreg is a vector.
G_CONCAT_VECTORS was actually not the proper instruction when the source
vregs were scalars and the compiler would assert that the sources must
be vectors. Instead we want is to issue a G_BUILD_VECTOR when we are
in this situation.
This patch fixes that.

BumpPtrAllocator allocates in 4KiB chunks, which with any larger
project is going to result in a large number of allocations.
Increasing allocation size this way can save 10%-20% of symbol

Summary:
IOHandler needs to read lines of input from a lldb::File.
The way it currently does this using, FILE*, which is something
we want to avoid now. I'd prefer to just replace the FILE* code
with calls to File::Read, but it contains an awkward and
delicate workaround specific to ctrl-C handling on windows, and
it's not clear if or how that workaround would translate to
lldb::File.
So in this patch, we use use the FILE* if it's available, and only
fall back on File::Read if that's the only option.
I think this is a reasonable approach here for two reasons. First
is that interactive terminal support is the one area where FILE*
can't be avoided. We need them for libedit and curses anyway,
and using them here as well is consistent with that pattern.
The second reason is that the comments express a hope that the
underlying windows bug that's being worked around will be fixed one
day, so hopefully when that happens, that whole path can be deleted.

Currently when invoking lldb-test symbols -dump-ast it parses all the debug symbols and calls print(...) on the TranslationUnitDecl.
While useful the TranslationUnitDecl::print(...) method gives us a higher level view then the dump from ASTDumper which is what we get when we invoke dump() on a specific AST node.
The main motivation for this change is allow us to verify that the AST nodes we create when we parse DWARF. For example in order to verify we are correctly using DIFlagExportSymbols added by D66667

__builtin_assume_aligned takes a size_t which is a 32 bit int on
hexagon. Thus, the constant gets converted to a 32 bit value, resulting
in 0 not being a power of 2. This patch changes the constant being
