Previously, when leave was used in the except or finally block of a nested try block, it would jump back to the start of the except/finally block, resulting in an endless loop. This is fixed by jumping back to a label at the beginning of the try block, which is only visible from within the try block itself and from there to the end of the SEH block.
Fixes seh0055 testcase of MS SEH tests.
These tests come with a VS solution, because that is the only way to test against a known good system, as the required runtime functions (like _ftol) are statically linked from the VS runtime library.
* [COMPILER_APITEST] Import MS EH/SEH tests
Taken from https://github.com/microsoft/compiler-tests
* [CRT] Add missing declaration of _longjmpex
* [COMPILER_APITEST] Add cmake build files for MS SEH test
It is built as a static library
* [COMPILER_APITEST] Fix GCC build of MS SEH tests
There are a number of hacks in there now. Also the volatile hacks should be separated and sent upstream.
* [COMPILER_APITEST] Fix x64 build of MS SEH tests
* [COMPILER_APITEST] Fix clang build of MS SEH tests
* [COMPILER_APITEST] Include MS SEH tests
