[bug#40739] [PATCH 1/5] gnu: llvm-for-extempore: Update to 3.8.

[Giacomo Leidi <goodoldpaul@autistici.org>]

* gnu/packages/llvm.scm (llvm-for-extempore): Update to 3.8.
[source]: Use upstream patched source.
* gnu/packages/patches/llvm-for-extempore.patch: Delete due to source being
already patched.
* gnu/local.mk (dist_patch_DATA): Remove it.

-This patch to LLVM is required by the developers of the Extempore language.
-The following explanation was posted to the extemporelang@googlegroups.com
-mailing list:
-
-"There is an assumption in the parser that all definitions occur within the
-same compilation unit - i.e. the parser has local state about what has been
-parsed in this unit of work.  Extempore obviously does lots of little units
-rather than one big unit and this causes problems for named types that were
-defined in another unit - which they always are.  The patch simply checks the
-current module to see if the type has been previously defined, and intervenes
-appropriately if it has."
