[Wang Mingyu < wangmy@fujitsu.com>]

From: Wang Mingyu <wangmy@fujitsu.com>

add patches to fix compilation with GCC < 13

Add two patches to fix build failures when using older GCC:
- Fix typed enum syntax not supported by GCC 11.
- Fix variable declaration after case label not allowed by GCC 10.

+Subject: [PATCH] src/intel/compiler/jay: fix GCC 10 case label declaration
+ error
+
+GCC 10 (and earlier) does not allow a variable declaration immediately
+after a case label, because a label must be followed by a statement.
+
+  error: a label can only be part of a statement and a declaration is not a statement
+
+Wrap the case block for JAY_OPCODE_DESWIZZLE_ODD in braces to make the
+declaration a valid statement inside the block.
+
+Upstream-Status: Inappropriate [yocto host distro requirements]

+Subject: [PATCH] src/intel/compiler/jay/jay_ir.h: do not used typed enum
+
+This is a C23 feature and not supported by gcc < 13, which
+many host distros still have (e.g. Debian 12).
