This forces the code to call StringInit::get on the string early and
avoids storing duplicates in std::string and sometimes allows pointer
comparisons instead of string comparisons.

Building compiler-rt on Darwin produces dozens of meaningless warnings about object files having no symbols during static archive creation. This is very intentional as compiler-rt uses #ifdefs to conditionally compile platform-specific code, and we even have a .cpp source file that only contains static asserts to make sure the environment is configured right. On Linux, this situation is fine and no warning is produced. This patch adds a libtool version detection and if it's new enough, we'll use the -no_warning_for_no_symbols flag that suppresses this warning. Build logs should be much cleaner now!

Introduce new constructor for STRCONCAT binop with a shortcut that
immediately concatenates if the two arguments are StringInits.
Makes the QualifyName code more readable and tablegen 2-3% faster.

Currently the fast isel code emits an avx1 instruction sequence even with avx512. This is different than normal isel. A follow up commit will fix this.

The old implementation of add_llvm_tool_symlink could fail in odd ways when building out of tree. This version solves that problem by not using the LLVM_* variables, and instead reaeding the target's properties.

I think these intrinsics were added after the Commutative was added to most of the rest of the intrinsics and it must have been forgotten.

All these records are internalized and will live until exit. This makes
them perfect candidates for a fast BumpPtrAllocator.

This avoid an extra construction of a std::string (and a heap
allocation) when the caller only has a StringRef but no std::string at
hand.

Changes all static helper functions in MachOObjectFile.cpp that expect a

The variable was assigned to, but never used. The functions called did not
mutate state. Simplify the logic and remove the variable. Identified by gcc

Previously this pass was using up to 5% compile time in some cases which
is a bit much for what it is doing. The pass featured a full blown
data-flow analysis which in the default configuration was restricted to a
single block.
This rewrites the pass under the assumption that we only ever work on a
single block. This is done in a single pass maintaining a state machine
per general purpose register to catch LOH patterns.
