Craig Topper 81fe1fbf4a [X86][AutoUpgrade] Make some tweaks to reduce the number of nested if/else in the intrinsic upgrade code to avoid an MSVC compiler limit.
MSVC has a nesting limit of around 110-130. An if/else if/else if counts against this next level. The autoupgrade code consists a long chain of these checking matches against strings.

This commit moves some code to a helper function to move out a large if/else chain that was inside of one of the blocks into a separate function. There are more of these we could move or we could change some to lookup tables.

I've also merged together a few similar blocks in the outer chain. This should buy us some margin for a little bit.

Craig Topper 826f44b550 [TargetLowering][AMDGPU] Remove the SimplifyDemandedBits function that takes a User and OpIdx. Stop using it in AMDGPU target for simplifyI24.
As we saw in D56057 when we tried to use this function on X86, it's unsafe. It allows the operand node to have multiple users, but doesn't prevent recursing past the first node when it does have multiple users. This can cause other simplifications earlier in the graph without regard to what bits are needed by the other users of the first node. Ideally all we should do to the first node if it has multiple uses is bypass it when its not needed by the user we started from. Doing any other transformation that SimplifyDemandedBits can do like turning ZEXT/SEXT into AEXT would result in an increase in instructions.

Fortunately, we already have a function that can do just that, GetDemandedBits. It will only make transformations that involve bypassing a node.

This patch changes AMDGPU's simplifyI24, to use a combination of GetDemandedBits to handle the multiple use simplifications. And then uses the regular SimplifyDemandedBits on each operand to handle simplifications allowed when the operand only has a single use. Unfortunately, GetDemandedBits simplifies constants more aggressively than SimplifyDemandedBits. This caused the -7 constant in the changed test to be simplified to remove the upper bits. I had to modify computeKnownBits to account for this by ignoring the upper 8 bits of the input.

Julian Lettner a6d29024ed [TSan] Support Objective-C @synchronized with tagged pointers
Summary:
Objective-C employs tagged pointers, that is, small objects/values may be encoded directly in the pointer bits. The resulting pointer is not backed by an allocation/does not point to a valid memory. TSan infrastructure requires a valid address for `Acquire/Release` and `Mutex{Lock/Unlock}`.
This patch establishes such a mapping via a "dummy allocation" for each encountered tagged pointer value.

Armando Montanez 488545ef15 [elfabi] Add option to manually specify file read format
Although llvm-elfabi will attempt to read input files without needing the format to be manually specified, doing so has the potential to introduce extraneous errors that can hinder debugging (since multiple readers may fail in attempts to read the file). This change allows the input file format to be manually specified to force elfabi to use a single reader. This makes it easier to test and debug errors specific to a given reader.
