And what do you expect? That means including over 1.5MB of preprocessed
source, with over 5500 inline functions.

One thing which could be done is similar to what AARCH64 did for SVE/SVE2
builtins and just implement the majority of the intrinsics in the front-end.
The aarch64 target does this in the user include header:
#pragma GCC aarch64 "arm_sve.h"
Which just interjects the intrinsics as builtins at that point.
