[MASSMAIL]some LLVM function checks missing in meson - Mailing list pgsql-hackers

I have been checking the pg_config.h generated by configure and meson to 
see if there is anything materially different.  I found that

HAVE_DECL_LLVMCREATEGDBREGISTRATIONLISTENER and
HAVE_DECL_LLVMCREATEPERFJITEVENTLISTENER

are missing on the meson side.

Something like the below would appear to fix that:

diff --git a/meson.build b/meson.build
index 43fad5323c0..cdfd31377d1 100644
--- a/meson.build
+++ b/meson.build

  foreach c : decl_checks
    func = c.get(0)
    header = c.get(1)

I don't know what these functions do, but the symbols are used in the 
source code.  Thoughts?
