[ELF] - Do not ignore discarding of .rela.plt/.rela.dyn, allow doing custom layout for them.
Currently when we build input sections list in linker script
we ignore all rel[a] sections. That was done to support
scripts like .rela.dyn : { *(.rela.data) } for emit relocs.
Though as a result following scripts were also silently ignored:
/DISCARD/ : { *(.rela.plt)
/DISCARD/ : { *(.rela.dyn)
and we produced output with this sections. That is not ideal.
The solution this patch suggests is simple: do not ignore synthetic
rel[a] sections. That way we can enable common discarding logic
for them and report a proper error.

The approach is similar to ARM case, trap signal is used to communicate
memory tag check failure. int3 instruction is used to generate a signal,
access parameters are stored in nop [eax + offset] instruction immediately
following the int3 one
Had to add HWASan init on malloc because, due to much less interceptors
defined (most other sanitizers intercept much more and get initalized
via one of those interceptors or don't care about malloc), HWASan was not
initialized yet when libstdc++ was trying to allocate memory for its own
fixed-size heap, which led to CHECK-fail in AllocateFromLocalPool.
Also added the CHECK() failure handler with more detailed message and
stack reporting.

This one will be used to print statistics about lldb sessions

a clean reference on how a command should be implemented.
My future commits are going to populate this command and test
it.

[PM][FunctionAttrs] add NoUnwind attribute inference to PostOrderFunctionAttrs pass
Summary:
This was motivated by absence of PrunEH functionality in new PM.
It was decided that a proper way to do PruneEH is to add NoUnwind inference
into PostOrderFunctionAttrs and then perform normal SimplifyCFG on top.
This change generalizes attribute handling implemented for (a removal of)
Convergent attribute, by introducing a generic builder-like class
AttributeInferer
It registers all the attribute inference requests, storing per-attribute
predicates into a vector, and then goes through an SCC Node, scanning all
the instructions for not breaking attribute assumptions.
The main idea is that as soon all the instructions from all the functions
of SCC Node conform to attribute assumptions then we are free to infer
the attribute as set for all the functions of SCC Node.
It handles two distinct cases of attributes:
- those that might break due to derefinement of the function code
for these attributes we are allowed to apply inference only if all the
functions are "exact definitions". Example - NoUnwind.
- those that do not care about derefinement
for these attributes we are allowed to apply inference as soon as we see
any function definition. Example - removal of Convergent attribute.
Also in this commit:
* Converted all the FunctionAttrs tests to use FileCheck and added new-PM
invocations to them
* FunctionAttrs/convergent.ll test demonstrates a difference in behavior between
new and old PM implementations. Marked with FIXME.
* PruneEH tests were converted to new-PM as well, using function-attrs+simplify-cfg
combo as intended
* some of "other" tests were updated since function-attrs now infers 'nounwind'
even for old PM pipeline
* -disable-nounwind-inference hidden option added as a possible workaround for a supposedly
rare case when nounwind being inferred by default presents a problem

[Hexagon] Assume all extendable branches to be of size 8 in relaxation
The branch relaxation pass collects sizes of all instructions at the
beginning, before any changes have been made. It then performs one pass
over all branches to see which ones need to be extended. It does not
account for the case when a previously valid branch becomes out-of-range
due to relaxing other branches.
This approach fixes this problem by assuming from the beginning that
all extendable branches have been extended. This may cause unneeded
relaxation in some cases, but avoids iteration and recomputing instruction
sizes.
