[sanitizer_common] Several Solaris procmaps fixes
Since the introduction of GoogleTest sharding in D122251
<https://reviews.llvm.org/D122251>, some of the Solaris sanitizer tests
have been running extremly long (up to an hour) while they took mere
seconds before. Initial investigation suggests that massive lock
contention in Solaris procfs is involved here.
However, there's an easy way to somewhat reduce the impact: while the
current `ReadProcMaps` uses `ReadFileToBuffer` to read `/proc/self/xmap`,
that function primarily caters to Linux procfs reporting file sizes of 0
while the size on Solaris is accurate. This patch makes use of that,
reducing the number of syscalls involved and reducing the runtime of
affected tests by a factor of 4.
Besides, it handles shared mappings and doesn't call `readlink` for unnamed
map entries.
Tested on `sparcv9-sun-solaris2.11` and `amd64-pc-solaris2.11`.

[LSR] Allow already invariant operand for ICmpZero matching [try 2]
Changes since initial commit:
* Wrapping a pointer in an SCEV unknown hides the base, and SCEV is only able to compute a subtraction when the bases are known to be equal. This results in a SCEVCouldNotCompute flowing forward and triggering asserts. Test case added in
d767b392.
* isLoopInvariant returns true for instructions outside the loop, but not necessarily *above* the loop. Since this code is allowed to visit uses of an IV outside of a loop, we have to make sure the operands of the compare are both invariant and dominating the header. Test case added in
2aed3cdb.
Original commit message follows...
The ICmpZero matching is checking to see if the expression is loop invariant per SCEV and expandable. This allows expressions inside the loop which can be made loop invariant to be seamlessly expanded, but is overly conservative for expressions which already *are* loop invariant.
As a simple justification for why this is correct, consider a loop invariant urem as RHS vs an alternate function with that same urem wrapped inside a helper call. Why would it be legal to match the later, but not the former?

[LSR] Allow already invariant operand for ICmpZero matching
The ICmpZero matching is checking to see if the expression is loop invariant per SCEV and expandable. This allows expressions inside the loop which can be made loop invariant to be seamlessly expanded, but is overly conservative for expressions which already *are* loop invariant.
As a simple justification for why this is correct, consider a loop invariant urem as RHS vs an alternate function with that same urem wrapped inside a helper call. Why would it be legal to match the later, but not the former?

[Clang] Add a new clang option "-ftime-trace=<value>"
The time profiler traces the stages during the clang compile
process. Each compiling stage of a single source file
corresponds to a separately .json file which holds its
time tracing data. However, the .json files are stored in the
same path/directory as its corresponding stage's '-o' option.
For example, if we compile the "demo.cc" to "demo.o" with option
"-o /tmp/demo.o", the time trace data file path is "/tmp/demo.json".
A typical c++ project can contain multiple source files in different
path, but all the json files' paths can be a mess.
The option "-ftime-trace=<value>" allows you to specify where the json
files should be stored. This allows the users to place the time trace
data files of interest in the desired location for further data analysis.
Usage:
- clang/clang++ -ftime-trace ...
- clang/clang++ -ftime-trace=the-directory-you-want ...
- clang/clang++ -ftime-trace=the-directory-you-want/ ...
- clang/clang++ -ftime-trace=the-full-file-path-you-want ...

[lldb] [llgs] Send process output asynchronously in non-stop mode
Introduce a new %Stdio notification category and use it to send process
output asynchronously when running in non-stop mode. This is an LLDB
extension since GDB does not use the 'O' packet for process output,
just for replies to 'qRcmd' packets.
Using the async notification mechanism implies that only the first
output packet is sent immediately to the client. The client needs
to request subsequent notifications (if any) using the new vStdio packet
(that works pretty much like vStopped for the Stop notification queue).
The packet handler in lldb-server tests is updated to handle the async
stdio packets in addition to the regular O packets. However, due
to the implications noted above, it can only handle the first output
packet sent by the server. Subsequent packets need to be explicitly
requested via vStdio.
