Call type not being respected

[comex]

Version and Platform (required):

• Binary Ninja Version: 3.5.4307-dev (390387c6)
• OS: macOS
• OS Version: 13.3 (22E252)
• CPU Architecture: arm64

The binary being reverse engineered is also arm64.

Bug Description:

I used Override Call Type on a blr instruction, specifying a function type with 10 arguments. Yet the HLIL view only shows 8 arguments.

Steps To Reproduce:

1. Open this ELF and make a function at address 0.
2. Set the blr at 0xe8 to have this type with 10 arguments:

int64_t calltarget(int64_t arg1, int64_t arg2, int64_t* arg3, int64_t* arg4, int32_t* arg5, int32_t arg6, int64_t* arg7, int32_t arg8, int32_t* arg9, int32_t* arg10)

3. Note that the decompiled call shows only 8 arguments:

int64_t x0_4 = x8_3(arg1, arg3, arg5, x7, arg8, 1, &var_a0, 2)

The extra arguments are stored to the stack at 0xc8, but this is not being made part of the call for some reason.
