64cd55a126 Update programmers manual to cover llvm::function_ref, and add a note to the 
coding standard suggesting using it instead of the (unavailable) std::function.

f0e7f76933 [Build] Add rule to generate fully-expanded .td file 
I found it useful in the past and now again to have a version of the .td file
where all the records are expanded.  This adds a makefile rule to generate
this on demand.

40a1b74db6 PR19598: Provide the ability to RAUW a declaration with itself, creating a non-temporary copy and using that to RAUW. 
Also, provide the ability to create temporary and non-temporary
declarations, as not all declarations may be replaced by definitions
later on.

This provides the necessary infrastructure for Clang to fix PR19598,
leaking temporary MDNodes in Clang's debug info generation.

9ad48c11b1 Fix i128 div/mod on mingw64 
The Win64 docs are very clear that anything larger than 8 bytes is
passed by reference, and GCC MinGW64 honors that for __modti3 and
friends.

9331beb910 Include intrin.h before windows.h as a workaround for the x64 self-host 
On x64, windows.h doesn't include intrin.h for intrinsics.  It just
declares them in the global namespace and uses them, expecting the
compiler to lower it as a builtin.  We basically need to do this in
clang, eventually.

05da4dd998 Improve 'tail' call marking in TRE. A bootstrap of clang goes from 375k calls marked tail in the IR to 470k, however this improvement does not carry into an improvement of the call/jmp ratio on x86. The most common pattern is a tail call + br to a block with nothing but a 'ret'. 
The number of tail call to loop conversions remains the same (1618 by my count).

The new algorithm does a local scan over the use-def chains to identify local "alloca-derived" values, as well as points where the alloca could escape. Then, a visit over the CFG marks blocks as being before or after the allocas have escaped, and annotates the calls accordingly.
