Fix warnings about variables that are set but only used in debug mode
Add void casts to mark the variables used, next to the places where
they are used in assert or `LLVM_DEBUG()` expressions.

[SampleFDO] Place the discriminator flag variable into the used list.
We create flag variable "__llvm_fs_discriminator__" in the binary
to indicate that FSAFDO hierarchical discriminators are used.
This variable might be GC'ed by the linker since it is not explicitly
reference. I initially added the var to the use list in pass
MIRFSDiscriminator but it did not work. It turned out the used global
list is collected in lowering (before MIR pass) and then emitted in
the end of pass pipeline.
Here I add the variable to the use list in IR level's AddDiscriminators
pass. The machine level code is still keep in the case IR's
AddDiscriminators is not invoked. If this is the case, this just use
-Wl,--export-dynamic-symbol=__llvm_fs_discriminator__
to force the emit.

[SampleFDO] New hierarchical discriminator for FS SampleFDO (ProfileData part)

[SampleFDO] New hierarchical discriminator for FS SampleFDO (ProfileData part)
This patch was split from https://reviews.llvm.org/D102246
[SampleFDO] New hierarchical discriminator for Flow Sensitive SampleFDO
This is mainly for ProfileData part of change. It will load
FS Profile when such profile is detected. For an extbinary format profile,
create_llvm_prof tool will add a flag to profile summary section.
For other format profiles, the users need to use an internal option
(-profile-isfs) to tell the compiler that the profile uses FS discriminators.
This patch also simplified the bit API used by FS discriminators.

[SampleFDO] New hierarchical discriminator for Flow Sensitive SampleFDO
This patch implements first part of Flow Sensitive SampleFDO (FSAFDO).
It has the following changes:
(1) disable current discriminator encoding scheme,
(2) new hierarchical discriminator for FSAFDO.
For this patch, option "-enable-fs-discriminator=true" turns on the new
functionality. Option "-enable-fs-discriminator=false" (the default)
keeps the current SampleFDO behavior. When the fs-discriminator is
enabled, we insert a flag variable, namely, llvm_fs_discriminator, to
the object. This symbol will checked by create_llvm_prof tool, and used
to generate a profile with FS-AFDO discriminators enabled. If this
happens, for an extbinary format profile, create_llvm_prof tool
will add a flag to profile summary section.
