[llvm] [NFC] Remove the unused hasMinSize() (PR #133838)

[Ningning Shi 史宁宁 via llvm-commits]

https://github.com/shining1984 created https://github.com/llvm/llvm-project/pull/133838

The 'hasOptSize()' is 'hasFnAttribute(Attribute::OptimizeForSize) || hasMinSize()', so we don't need another 'hasMinSize()'.

Subject: [PATCH] [NFC] Remove the unused hasMinSize()

The 'hasOptSize()' is 'hasFnAttribute(Attribute::OptimizeForSize) || hasMinSize()', so we don't
need another 'hasMinSize()'.
