So I could get ICC to produce them but clang does not.

Interesting it was mentioned here:
https://gcc.gnu.org/legacy-ml/gcc/2003-12/msg00336.html
I wonder if we could mark the BLOCK as being the try block and then output
DW_TAG_try_block instead of DW_TAG_lexical_block . Likewise for catch.
Maybe I will give that a go for GCC 15. Though I might be only handle the C++
front-end. Others will need to handle other FEs.

So for space, on LP64 (and LLP64) hosts, there is a free 32bits in the BLOCK
structure:
```
tree chain;
unsigned block_num;
location_t locus; // unsigned
location_t end_locus; // unsigned
tree vars;
```
So I can at least add a 3bit field without increasing the size too.

for try blocks, I do need the catch blocks so do it as the siblings.
For catch blocks, the child will be type that is being caught as a
DW_TAG_formal_parameter/DW_TAG_unspecified_parameters .

Note DW_TAG_unspecified_parameters is for the catch(...) case.
I am adding this more for my usage when I am coding this up to make sure I
understand how this works.

for the VAR_DECL of the catch, I think I should be able to use
gen_formal_parameter_die.
This means the block structure will need to grow since I need another tree
here. Or maybe not. Since there seems like there are 2 BLOCKs here for the
catch.
