Function definition may have uninstantiated body
Current implementation of `FunctionDecl::isDefined` does not take into
account redeclarations that do not have bodies, but the bodies can be
instantiated from corresponding templated definition. This behavior does
not allow to detect function redefinition in the cases where friend
functions is defined in class templates. For instance, the code:
```
template<typename T> struct X { friend void f() {} };
X<int> xi;
void f() {}
```

declaration of the friend `f` is created when the containing template
`X` is instantiated, but it does not have a body as per 14.5.4p4
because `f` is not odr-used.

[GlobalISel][AArch64] Adding -disable-gisel-legality-check CL option
Currently it's impossible to test InstructionSelect pass with MIR which
is considered illegal by the Legalizer in Assert builds. In early stages
of porting an existing backend from SelectionDAG ISel to GlobalISel,
however, we would have very basic CallLowering, Legalizer, and
RegBankSelect implementations, but rather functional Instruction Select
with quite a few patterns selectable due to the semi-automatic porting
process borrowing them from SelectionDAG ISel.
As we are trying to define legality as a property of being selectable by
the instruction selector, it would be nice to be able to easily check
what the selector can do in its current state w/o the legality check
provided by the Legalizer getting in the way.
It also seems beneficial to have a regression testing set up that would
not allow the selector to silently regress in its support of the MIR not
supported yet by the previous passes in the GlobalISel pipeline.
This commit adds -disable-gisel-legality-check command line option to
llc that disables those legality checks in RegBankSelect and
InstructionSelect passes.
It also adds quite a few MIR test cases for AArch64's Instruction
Selector. Every one of them would fail on the legality check at the
moment, but will select just fine if the check is disabled. Every test
MachineFunction is intended to exercise a specific selection rule and
that rule only, encoded in the MachineFunction's name by the rule's

[MIRParser] Accept overloaded intrinsic names w/o type suffixes
Function::lookupIntrinsicID is somewhat forgiving as it comes to
overloaded intrinsics' names: it returns an ID as soon as the name
provided has a prefix that matches a registered intrinsic's name w/o
actually checking that the rest of the name encodes all the concrete arg
types, let alone that those types are compatible with the intrinsic's
definition.
That's probably fine and comes in handy in MIR serialization: we don't
care about IR types at MIR level and every intrinsic should be
selectable based on its ID and low-level types (LLTs) of its operands,
including the overloaded ones, so there is no point in serializing
mangled IR types as part of the intrinsic's name.
However, lookupIntrinsicID is somewhat inconsistent in its forgiveness:
if the name provided is actually an exact match, it will refuse to
return the ID if the intrinsic is overloaded. There is probably no
real reason for that and it renders MIRParser incapable to deserialize
MIR MIRPrinter serialized.

[InstCombine] Split the FP constant code out of lookThroughFPExtensions and use nullptr as a sentinel
Currently this code's control flow very much assumes that there are no meaningful checks after determining that it's a ConstantFP. So whenever it wants to stop it just does "return V". But V is also the variable name it uses when it wants to return a new value. So 'return V' appears multiple times with different meanings.
This patch just moves all the code into a helper function and returns nullptr when it wants to stop.

Fix llvm-config --system-libs output on FreeBSD and NetBSD
Summary:
For various reasons, CMake's detection mechanism for `backtrace()`
returns an absolute path `/usr/lib/libexecinfo.so` on FreeBSD and
NetBSD.
Since `tools/llvm-config/CMakeLists.txt` only checks if system
libraries start with `-`, this causes `llvm-config --system-libs` to
produce the following incorrect output:
```
-lrt -l/usr/lib/libexecinfo.so -ltinfo -lpthread -lz -lm
```
Fix it by removing the path and the `lib` prefix, to make it look like a
regular short library name, suitable for appending to a `-l` link flag.
This also fixes the `Bindings/Go/go.test` test case, since that always
died with "unable to find library -l/usr/lib/libexecinfo.so".

While the hook is not needed for program correctness (the profile
