Describe the bug

i write an YUL file, and i hope the forge can compile it for me. but it fails with the corresponding error:

(base) ➜  temp git:(master) ✗ forge b  
[⠢] Compiling...
[⠢] Compiling 10 files with 0.8.16
[⠆] Solc 0.8.16 finished in 1.99s
[⠰] Compiling 1 files with 0.8.16
[⠔] Solc 0.8.16 finished in 6.38ms
Error: 
Compiler run failed
Field "settings.remappings" cannot be used for Yul.

and also, i create an repo to replicate this error, please check:

@bixia this error comes straight from the compiler since the remappings to forge-std & ds-test are added by default.

@mattsse @gakonst wdyt about doing a separate compiler run for .yul files if there are any detected?

[mattsse]

that makes sense and another sanitize call on the CompilerInput to make it work with yul

@mattsse sry for no update, i actually found the PR with support for yul in ethers that did that. i'll put out the PR shortly which omits remappings and revertStrings for yul
