Justin Bogner efc3fbf6a2 Verifier: Disallow a line number without a file in DISubprogram
A line number doesn't make much sense if you don't say where it's
from. Add a verifier check for this and update some tests that had
bogus debug info.

Dehao Chen 554f500ae2 Before sample pgo annotation, do not inline a function that has no debug info. (NFC)
If there is no debug info in the callee, inlining it will not help annotator. This avoids infinite loop as reported in PR/31119.

Dehao Chen 20866ed57e Handle early inline for hot callsites that reside in the same basic block.
Summary: Callsites in the same basic block should share the same hotness. This patch checks for the hottest callsite in the same basic block, and use the hotness for all callsites in that basic block for early inline decisions. It also fixes the test to add "-S" so theat the "CHECK-NOT" is actually checking the content.

Dehao Chen 41cde0b986 Handle Invoke during sample profiler annotation: make it inlinable.
Summary: Previously we reline on inst-combine to remove inlinable invoke instructions. This causes trouble because a few extra optimizations are schedule early that could introduce too much CFG change (e.g. simplifycfg removes too much control flow). This patch handles invoke instruction in-place during sample profile annotation, so that we do not rely on instcombine to remove those invoke instructions.
