[sanitizer coverage] when adding a bb trace instrumentation, do it instead, not in addition to, regular coverage. Do the regular coverage in the run-time instead

[sancov] Disable sanitizer coverage on functions using SEH

Splitting basic blocks really messes up WinEHPrepare. We can remove this
change when SEH uses the new EH IR.

[SanitizerCoverage] Use llvm::getDISubprogram() to get location of the entry basic block.

DebugLoc::getFnDebugLoc() should soon be removed. Also,
getDISubprogram() might become more effective soon and wouldn't need to
scan debug locations at all, if function-level metadata would be emitted
by Clang.

Simplify IRBuilder::CreateCall* by using ArrayRef+initializer_list/braced init only

SanitizerCoverage: Use `createSanitizerCtor` to create ctor and call init

Second attempt; instead of using a named local variable, passing
arguments directly to `createSanitizerCtorAndInitFunctions`
