George Rimar	c44a23f8f4	[LLD][ELF] - Linkerscript: fix FILL() expressions handling. ... D64130 introduced a bug described in the following message: https://reviews.llvm.org/D64130#1571560 The problem can happen with the following script: SECTIONS { .out : { ... FILL(0x10101010) *(.aaa) ... } The current code tries to read (0x10101010) as an expression and does not break when meets *, what results in a script parsing error. In this patch, I verify that FILL command's expression always wrapped in (). And at the same time =<fillexp> expression can be both wrapped or unwrapped. I checked it matches to bfd/gold.

George Rimar	0810f16fb9	[LLD][ELF] - Linkerscript: add a support for expressions for section's filling ... Imagine the script: .section: { ... } = FILL_EXPR LLD assumes that FILL_EXPR is a number, and does not allow it to be an expression. Though that is allowed by specification: https://sourceware.org/binutils/docs-2.32/ld/Output-Section-Fill.html This patch adds a support for cases when FILL_EXPR is simple math expression.
