I removed this in r316797 because the coverage report showed no coverage and I thought it should have been handled by the auto generated table. I now see that there is code that bypasses the table if the shift amount is out of bounds.
This adds back the code. We'll codegen out of bounds i8 shifts to effectively (amount & 0x1f). The 0x1f is a strange quirk of x86 that shift amounts are always masked to 5-bits(except 64-bits). So if the masked value is still out bounds the result will be 0.

Summary:
To make this build work, I needed to add detection code for the pthread
library. This is necessary, because we have direct calls to these
libraries (instead of going through llvm) and in the standalone build we
cannot rely on llvm to detect these for us. In a standalone non-dylib
build this was accidentaly working because these libraries were pulled
in as an interface dependency of the .a files, but in a dylib build
these are no longer part of the link interface, and so we need to add
them explicitly.

[SymbolFilePDB] Rewrite ParseTypes method
Summary:
The types for the compiland's children are parsed when parsing types for a PDB compiland. Global types also need to be parsed but unfortunately PDBs do not have compiland information about each global type. So we parse them all on the first call to ParseTypes.
If a sc.function is provided then parse the types for that function. Otherwise parse the types for the overall sc.comp_unit.
The ParseTypes method can be very slow if a program has a long list of compile units containing needed modules. Debugging clang-cl with lldb will show the problem.
