This function seems target-independent so far: all the target-specific behaviour
is isolated in the CCAssignFn and the ValueHandler (which we're also extracting
into the generic CallLowering).
The intention is to use this in the ARM backend.

Include component in install rules for Sphinx targets. Based on
a similar suggestion for other doc targets in D24935.

A debug build of AsmMatcherEmitter would use a quadratic algorithm to
check whether std::stable_sort() actually sorted. Let's hope the authors
of our C++ standard library did that testing for us. Removing the check
gives a 3x speedup in the X86 case.

This may seem unusual, but makes most debug tblgen builds ~10% faster.
Usually we wouldn't care about speed that much in debug builds, but for
tblgen that also translates into build time.

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.

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
non-null MachOObjectFile pointer to take a reference instead.

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

Add an optional parameter to `llvm_install_symlink` which allows the symlink
installation to be placed into a specific component rather than the default
value.

"Lookup" is a noun ("lookup table"), "look up" is a verb ("look up
'table' in the dictionary").
