We had a bug where if we had forked (in the ProcessLauncherPosixFork)
while another thread was writing a log message, we would deadlock. This
happened because the fork child inherited the locked log rwmutex, which

disable all log channels.

[Hexagon] Handling of new HVX flags and target-features

This patch has the following changes
A new flag "-mhvx-length={64B|128B}" is introduced to specify the length of the vector.
Previously we have used "-mhvx-double" for 128 Bytes. This adds the target-feature "+hvx-length{64|128}b"

The "-mhvx" flag must be provided on command line to enable HVX for Hexagon. If no -mhvx-length flag
is specified, a default length is picked from the arch mentioned in this priority order from either -mhvx=vxx
or -mcpu. For v60 and v62 the default length is 64 Byte. For unknown versions, the length is 128 Byte. The
-mhvx flag adds the target-feature "+hvxv{hvx_version}"

The 64 Byte mode is soon going to be deprecated. A warning is emitted if 64 Byte is enabled. A warning is
still emitted for the default 64 Byte as well. This warning can be suppressed with a -Wno flag.

The "-mhvx-double" and "-mno-hvx-double" flags are deprecated. A warning is emitted if the driver sees
them on commandline. "-mhvx-double" is an alias to "-mhvx-length=128B"

The compilation will error out if -mhvx-length is specified with out an -mhvx/-mhvx= flag

The macro HVX_LENGTH is defined and is set to the length of the vector.
Eg: #define HVX_LENGTH 64

The macro HVX_ARCH is defined and is set to the version of the HVX.

[Hexagon] New HVX target features.

This patch lets the llvm tools handle the new HVX target features that
are added by frontend (clang). The target-features are of the form
"hvx-length64b" for 64 Byte HVX mode, "hvx-length128b" for 128 Byte mode HVX.
"hvx-double" is an alias to "hvx-length128b" and is soon will be deprecated.
The hvx version target feature is upgated form "+hvx" to "+hvxv{version_number}.
Eg: "+hvxv62"

For the correct HVX code generation, the user must use the following
target features.
For 64B mode: "+hvxv62" "+hvx-length64b"
For 128B mode: "+hvxv62" "+hvx-length128b"

Clang picks a default length if none is specified. If for some reason,
no hvx-length is specified to llvm, the compilation will bail out.
There is a corresponding clang patch.

check_clang_tidy.py currently only handles C and C++ source files.

This extends the logic to also handle Objective-C (.m) and
Objective-C++ (.mm) files.

However, by default, clang compiles .m/.mm files using Objective-C 1.0
syntax. Objective-C 2.0 has been the default in Xcode for about 10
years, and Objective-C Automatic Reference Counting (ARC) for about 6
years, so this enables both by default.

(Clients which actually want to test clang-tidy checks for Objective-C
 1.0 or non-ARC files can pass custom flags to check_clang_tidy.py
 after --, which will disable the Objective-C 2.0 and ARC flags).

I did not add logic to handle running clang-tidy on Objective-C header
files alone; they also use the .h file extension, so we'd need to
