[libc][math] Fix pow() subnormal base exponent computation (#198134)
For subnormal inputs, get_exponent() returns -1023. The code subtracted
64 after normalizing but didn't recompute e_x from the normalized value.
This set e_x to -1087 for every subnormal.
To fix, compute e_x from the normalized value.
powf() doesn't have this bug because it adds
`x_u >> FloatBits::FRACTION_LEN` to ex, where x_u is `x_u =
FloatBits(x).uintval();` with `x` being the normalized value. Added
subnormal base tests for powf to show that it works fine as-is.
Fixes #197212.
[llvm-debuginfo-analyzer] Fix missed 'else' (LVCodeViewReader / LVDWARFReader) (#192923)
Issues found PVS studio static analyzer.
LVCodeViewReader.cpp. PR for #170117.
4. Potent UB: manipulation of invalid object.
The PVS-Studio warning: V519 The 'FeaturesValue' variable is assigned
values twice successively.
The original patch caused fail tests for linker error and it was reverted.
This PR include original (#188578) + necessary edit in CMakeList.

[CUF] Fix CompilerGeneratedNamesConversion renaming managed companion globals
CUFAddConstructor creates a companion pointer global (e.g. foo.managed.ptr)
for each non-allocatable managed variable. When CompilerGeneratedNamesConversion
ran after CUFAddConstructor, it replaced the dots with 'X',
so CUFOpConversionLate could no longer find the companion by name and fell back
to CUFGetDeviceAddress with the wrong host pointer, causing cudaErrorInvalidSymbol.
Fix: mark the companion global with a cuf.managed_ptr unit attribute in
CUFAddConstructor and skip it in CompilerGeneratedNamesConversionPass.

devel/electron42: Add port: Build cross-platform desktop apps with JavaScript, HTML, and CSS
Build cross platform desktop apps with JavaScript, HTML, and CSS.
It's easier than you think.
If you can build a website, you can build a desktop app. Electron is a
framework for creating native applications with web technologies like
JavaScript, HTML, and CSS. It takes care of the hard parts so you can
focus on the core of your application.

[BPF] Remove getMaxNumArgs() from BPFTargetTransformInfo (#198223)
The function getMaxNumArgs() hardcoded the maximum number of function
arguments to 5. LLVM now supports more than 5 arguments with stack
argument support. Remove this leftover.
[mlir][linalg] Add splat transpose canonicalization patterns (#195991)
All elements in a dense splat are identical, transposing it only changes
the shape, but still maintaining the value. Add a pattern where it would
replace the `linalg.transpose` of a splat constant with a
`arith.constant` of the transposed result shape.

[Clang] Instantiate ParmVarDecls on-demand for FunctionParmPackExpr (#196919)
This is missed when we implemented CWG2369, where their instantiations
should be built in place when they are needed.
