[MachineIRBuilder] Fix an assertion failure with buildMerge
Teach buildMerge how to deal with scalar to vector kind of requests.
Prior to this patch, buildMerge would issue either a G_MERGE_VALUES when
all the vregs are scalars or a G_CONCAT_VECTORS when the destination
vreg is a vector. G_CONCAT_VECTORS was actually not the proper
instruction when the source vregs were scalars and the compiler would
assert that the sources must be vectors. Instead we want is to issue a
G_BUILD_VECTOR when we are in this situation.
This patch fixes that.

[GISel][CallLowering] Enable vector support in argument lowering
The exciting code is actually already enough to handle the splitting of
vector arguments but we were lacking a test case.
This commit adds a test case for vector argument lowering involving
splitting and enable the related support in call lowering.

[Mips][llvm-exegesis] Add a Mips target
The target does just enough to be able to run llvm-exegesis in latency
mode for at least some opcodes.

Commit f30ae7173958681b4b639e82e6530b3b047c1fde by Adrian Prantl
Set GNUC version in the LLDB expression parser.
This adapts LLDB for https://reviews.llvm.org/D68055.
Darwin's libC headers expect the GNUC macro to be set.
