This matches how ld.bfd works in practice; this fixes https://github.com/mstorsjo/llvm-mingw/issues/305. Adding a test for the new lib name combination that this allows, but also adding a few negative tests for combinations that aren't matched when -static is specified (because this change in itself didn't break any of the existing tests either). The logic in how ld.bfd looks for various libraries based on an -l<libname> argument is rather complex; the ldemul_open_dynamic_archive function looks for various combinations: https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=ld/emultempl/pep.em;h=e68d1e69f17ad73af065b6bed19ae89ded913172;hb=b51c2fec1da205ea3e7354cbb3e253018d64873c#l2066 This function is only called if looking for dynamic libraries (i.e. if -static wasn't specified): https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=ld/ldfile.c;h=731ae5f7aedcf921bd36a1b32a3e0f5bfa189071;hb=b51c2fec1da205ea3e7354cbb3e253018d64873c#l365 However even this function is skipped, it still looks for libraries in the form of "lib<libname>.a" (this is what lld did before): https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=ld/ldfile.c;h=731ae5f7aedcf921bd36a1b32a3e0f5bfa189071;hb=b51c2fec1da205ea3e7354cbb3e253018d64873c#l440 But it also calls a format specific function called ldemul_find_potential_libraries, which for PE targets looks for files named "<libname>.lib": https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=ld/emultempl/pep.em;h=e68d1e69f17ad73af065b6bed19ae89ded913172;hb=b51c2fec1da205ea3e7354cbb3e253018d64873c#l2175 Differential Revision: https://reviews.llvm.org/D135651
