Serge Pavlov 4d20e31f73 [FPEnv] Intrinsic llvm.roundeven
This intrinsic implements IEEE-754 operation roundToIntegralTiesToEven,
and performs rounding to the nearest integer value, rounding halfway
cases to even. The intrinsic represents the missed case of IEEE-754
rounding operations and now llvm provides full support of the rounding
operations defined by the standard.

Eric Christopher cee313d288 Revert "Temporarily Revert "Add basic loop fusion pass.""
The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

Eric Christopher a863435128 Temporarily Revert "Add basic loop fusion pass."
As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

Evandro Menezes 4b86c474ff [TargetLibraryInfo] Update run time support for Windows
It seems that the run time for Windows has changed and supports more math
functions than it used to, especially on AArch64, ARM, and AMD64.

Fixes PR40541.

Evandro Menezes ff5527718d [PATCH] [TargetLibraryInfo] Update run time support for Windows
It seems that the run time for Windows has changed and supports more math
functions than before.  Since LLVM requires at least VS2015, I assume that
this is the run time that would be redistributed with programs built with
Clang.  Thus, I based this update on the header file `math.h` that
accompanies it.

This patch addresses the PR40541.  Unfortunately, I have no access to a
Windows development environment to validate it.

Vedant Kumar f6c0b41fb7 [InstCombine] Avoid creating mis-sized dbg.values in commonCastTransforms()
This prevents InstCombine from creating mis-sized dbg.values when
replacing a sequence of casts with a simpler cast. For example, in:

  (fptrunc (floor (fpext X))) -> (floorf X)

We no longer emit dbg.value(X) (with a 32-bit float operand) to describe
(fpext X) (which is a 64-bit float).

This was diagnosed by the debugify check added in r335682.

Craig Topper 18799f4c07 [InstCombine] Allow fptrunc (fpext X)) to be reduced to a single fpext/ftrunc
If we are only truncating bits from the extend we should be able to just use a smaller extend.

If we are truncating more than the extend we should be able to just use a fptrunc since the presense of the fpextend shouldn't affect rounding.

Meador Inge 193e035b9c instcombine: Migrate math library call simplifications
This patch migrates the math library call simplifications from the
simplify-libcalls pass into the instcombine library call simplifier.

I have typically migrated just one simplifier at a time, but the math
simplifiers are interdependent because:

   1. CosOpt, PowOpt, and Exp2Opt all depend on UnaryDoubleFPOpt.
   2. CosOpt, PowOpt, Exp2Opt, and UnaryDoubleFPOpt all depend on
      the option -enable-double-float-shrink.

These two factors made migrating each of these simplifiers individually
more of a pain than it would be worth.  So, I migrated them all together.
