This patch uses one bit in profile version to differentiate Clang
instrumentation and IR level instrumentation profiles.
PGOInstrumenation generates a COMDAT variable __llvm_profile_raw_version so
that the compiler runtime can set the right profile kind.
For Maco-O platform, we generate the variable as linkonce_odr linkage as
COMDAT is not supported.
PGOInstrumenation now checks this bit to make sure it's an IR level
instrumentation profile.
The patch was submitted as r260164 but reverted due to a Darwin test breakage.

This reduces sizes of instrumented object files, final binaries,
process images, and raw profile data.
The format of the indexed profile data remain the same.

With this patch, the profile summary data will be available in indexed
profile data file so that profiler reader/compiler optimizer can start
to make use of.

For the struct with trailing objects, define
a member operator delete. Without this, the program
will fail when -fsized-deallocation option is used
where the wrong size will be passed to the global
delete operator.

This is the last step to enable profile runtime to share the same value prof
data format and reader/writer code with llvm host tools. The VP related
data structures are moved to a section in InstrProfData.inc enabled with macro
INSTR_PROF_VALUE_PROF_DATA, and common API implementations are enabled with
INSTR_PROF_COMMON_API_IMPL. There should be no functional change.

1. move const qualifier out of raw header field type as runtime use of the header
needs to initialze the fields
2. use C style casting for integer types.

In profile runtime implementation for Darwin, Linux and FreeBSD, the
names of sections holding profile control/counter/naming data need
to be known by the runtime in order to locate the start/end of the
data. Moving the name definitions to the common file to specify the
connection.

Add more complete description of the content and structure
of the template file. Made the comment in C style to be
shared by C runtime. Also enhance the file structure so
that it can included as standalone header for common
definitions.

This change introduces an instrumentation intrinsic instruction for
value profiling purposes, the lowering of the instrumentation intrinsic
and raw reader updates. The raw profile data files for llvm-profdata
testing are updated.

With this change, instrumentation code and reader/write
code related to profile data structs are kept strictly
in-sync. THis will be extended to cfe and compile-rt
references as well.

Changing PGO data format layout can be a pain. Many different places need
to be touched and kept in sync. Failing to do so usually results in errors
very time consuming to debug.
This file is intended to be the master file that defines the layout of the
core runtime data structures. Currently only two structure is covered: Per
function ProfData structure and the function record structure used in
coverage mapping.
No client code has been made yet, so this commit is NFC.
